VCF on November the 24th

On November the 24th Kristine Jørgensen will give a talk at VCF, with the title "Gameworld Interfaces".

Abstract

Designing so-called “invisible” interfaces that are integrated into the gameworld is a trend in modern game user interface design, and debates about the superiority of such interfaces frequently appear in game developer discourse. At the same time certain genres do not seem to pay this trend any attention and continue to use a lot of screen space on heavy overlays. While proponents of “invisible” interfaces believe that this approach provides the greatest sense of involvement for the player because the fiction appears unmediated, defenders of the second approach believe that clear information is necessary for overview and control and therefore a support for involvement. In this presentation I will discuss the main points in my monograph Gameworld Interfaces (MIT Press 2013). At the core of my argument is the idea that regardless of how the user interface is presented in games, it is a necessity to be able to present gameplay relevant system information to the player. For this reason, the conflict is not about whether or not to have an interface at all, but how to present system information in a way that is clear and communicative at the same time as it is elegant and takes up as little screen space as possible considering the information needs of the specific game.

Kristine Jørgensen is professor in media studies at UiB. She has been studying videogames since 2002 and is the author of Gameworld Interfaces and A Comprehensive Study of Sound in Computer Games. She is currently project manager of the RCN Young Research Talents project Games and Transgressive Aesthetics, and is head of the bachelor and master program in media and interaction design located in Media City Bergen.

VCF on September the 15th

On September the 15th Hanneke Meijer will give a talk at VCF, with the title "3D Imaging of Museum Collections".

Abstract

3D imaging techniques can provide a range of exciting opportunities for museum collections, research, exhibits, education and outreach. In this talk, I will highlight some of the potential uses of 3D imaging techniques for the Bergen University Museum. For instance, digital models of specimens can reduce damage that occurs when delicate or rare specimens are handled by researchers. Rather than loaning specimens to researchers, (high-res) 3D models of specimens can easily be shared with researchers worldwide, thereby facilitating research and reducing the need for travel. Furthermore, with only a small portion of collections on display in museum exhibits, digitization affords the opportunity to bring the remainder of the collection into the virtual light and allows the public to interact with museum collections. Finally, with 3D printing, educators can integrate 3D technologies into their classrooms.

Hanneke Meijer is an Associate Professor and Curator of Osteology at the Natural History Museum in Bergen. She is a vertebrate paleontologist with a background in vertebrate functional morphology and an interest in insular evolution, biogeography, paleoecology and extinction. Her research focuses on dispersal, turnover and extinction of prehistoric bird communities. A main focus of her work is Island Southeast Asia and Mauritius, where she uses fossil bird remains to document prehistoric avian biodiversity and the impact of natural and non-natural disturbances on an insular ecosystem, but she also works on bird remains from Scandinavia and the Mediterranean.

VCF on May the 5th

On May the 5th Nils Martin Engebretsen will give a talk at VCF, with the title "Data visualization in society: creating meanings and feelings through the visualization of numbers".

Abstract

We witness today an increased use of data visualization (DV) in a number of fields and genres: in journalism, in education, in commerce and industry etc. DV – in the forms of colorful graphs, maps and diagrams – are used to inform, convince and tell stories, and they promise to make both statistical material and unstructured flowing data accessible and intelligible even for untrained users. New affordances of dynamics and interaction introduced by digital media technology, make the landscape of DV-design even more rich and complex, and call for new and updated descriptions, models for learning and investigations concerning semiotic qualities and social functions. Martin Engebretsen, professor at UiA and leader of the NFR-funded project INDVIL (Innovative Data Visualization and Visual-numeric Literacy) will share future plans and preliminary results from the project (see www.indvil.org) He will focus specifically on the use of DV on online news sites. The main questions are: What characterizes the use of data visualizations on major Scandinavian news sites today and how do they create meanings and feelings?

VCF on April the 7th

On April the 7th Tobias Isenberg will give a talk at VCF, with the title "Abstraction in Non-Photorealistic Rendering and Illustrative Visualizations".

Abstract

Abstraction is a concept that is fundamental in both non-photorealistic rendering (NPR) and (illustrative) visualization. In NPR, abstraction is introduced by choosing a subset of elements to depict, by simplifying the depicted elements, by choosing a particular style of depiction, or by even changing the underlying geometric model. Here, abstraction typically serves an aesthetic goal. In illustrative visualization, abstraction is often used to emphasize important parts and de-emphasize less important ones. Traditionally, however, most authors argue that by simply using an NPR style or by using methods from illustrative rendering they automatically abstract---only few approaches actually discuss how the abstraction is introduced, what types of abstraction exist, and how abstraction can be controlled. I will discuss three approaches that not only rely on abstraction but also allow users to control it. First, I will discuss an approach for the abstraction of visualizations of molecular structures in which a continuous abstraction space between structural abstraction, abstraction through spatial perception, and abstraction by means of "illustrativeness" is created. Users can navigate this space to adjust visualization to their specific needs. Then I will talk about the abstraction of brain connectivity though the contraction of fiber tracks based on local similarity. And finally, I will discuss an example from NPR in which different abstraction strategies are used to affect map data in order to create an abstract map representation that is guided by each person's individual aesthetics.

VCF on March the 10th

On March the 10th Thomas Spengler will give a talk at VCF, with the title "Weather and Climate, a Playground for Big Data and Visualisation".

Abstract

Weather and climate science is among the most demanding in terms of challenges for computation and data. Terabytes of data are produced every day for operational forecasting, but at the end most people are only interested in a few symbols on their favourite weather app worth a few kilobytes. I will touch on the principles of weather forecasting and the computational demands and challenges for data input and transfer. In particular, I will also focus on current research questions with respect to storm development and state-of-the-art analysis techniques, including feature detection and data reduction using theoretical assessments of the flow evolution. I will also highlight challenges in visualising our conceptual understanding of the workings of the weather and point to open questions regarding best use of the available data given the current research questions, also with respect to ensemble prediction. As an outlook, I will also touch on data availability at our institute for possible collaboration and close with open questions from the atmospheric science side.

VCF on February the 10th

On February the 10th Morten Fjeld will give a talk at VCF, with the title "Content Delivery for Tomorrow: From Vibrotactile Notifications to Mid-Air Displays".

Abstract

Vibrotactile notifications can be supportive as our visual attention is often overtaxed, both in mobile and fixed settings. In the first part of this talk, we investigate how users perceive spatiotemporal vibrotactile patterns on the arm, palm, thigh, and waist. Results of the first two experiments indicate that precise recognition of either position or orientation is difficult across multiple body parts. Nonetheless, users were able to distinguish whether two vibration pulses were from the same location when played in quick succession. Based on this finding, we designed eight spatiotemporal vibrotactile patterns and evaluated them in two additional experiments. In the second part of this talk, we present HaptiColor, an assistive wristband that encodes discrete color information into spatiotemporal vibrations to support colorblind users to recognize and compare colors. In the third part of this talk, we speculate around how advances in display technologies could soon make wearable mid-air displays—devices that present dynamic images floating in mid-air relative to a mobile user—available.

VCF on November the 18th

On November the 18th Alexander Lundervold will give a talk at VCF, with the title "Modeling the human larynx for simulation of airflow during exercise".

Abstract

Obstruction of the central airways is typically expressed by exercise-induced inspiratory symptoms (EIIS) and is an important cause of exercise induced dyspnea in young and otherwise healthy individuals. We are constructing a computational model for the larynx that will be used to simulate the airflow. The aim is to understand the larynx’s role for breathing problems: which obstructions leads to problems, and why. To obtain the proper laryngeal geometry we use a combination of MRI and CT data acquired at HUS and NMBU. Our computational model is based on image and laryngoscopy data, and constructed using COMSOL Multiphysics, a finite-element based software package widely used in computer-aided engineering. The simulations aim to uncover the effect of geometry changes in the supraglottic region on the characteristics of the airflow through the larynx.

On October the 14th Marc Baaden will give a talk at VCF, with the title "An update on seeing and touching molecules in motion through interactive molecular graphics".

Abstract

For several years now, our team pursues the goal to study complex molecular assemblies through interactive visualization, manipulation and analysis approaches to aid hypothesis generation and exploration of complex datasets. The UnityMol framework [1] forms a central tool for these investigations and is based on the Unity3D game engine. A first line of research tries to help with the 3D context, for instance through content-guided navigation, exploded views and semantic links between molecular objects and their analysis data [2]. Concerning the molecular representations, we extended the UnityMol repertoire to include specific visualizations for sugar molecules [3] and are now including coarse-grained systems by default. These are particularly apt for interactive simulations, even in the classroom or via crowdsourcing. A particular focus lies on the integration of dedicated hardware such as large, high-resolution display walls, or more recently head-mounted virtual reality headsets or augmented reality setups.

VCF on September the 30th

On September the 27th Marc Vaudel will give a talk at VCF, with the title "Analyzing Complex Biomedical Data to Improve Patient Care".

Abstract
High throughput sample characterization techniques like genomic sequencing have revolutionized modern patient care and led to the paradigms of personalized and precision medicine. However, comprehensive analytical approaches, the so-called omics fields, have also revealed the overwhelming complexity of biological systems, and require the interpretation of massive amounts of data. As a result, there is currently a major gap between what can be inferred from patient samples and what is actually used in the clinics. This presentation will introduce key concepts in using omics techniques for precision medicine, and underline some of the challenges associated with patient data interpretation. A particular emphasis will be given to the complexity of associating the omics data with disease mechanisms, and to the importance of making the results intelligible to all. Interactive data visualization plays a crucial role in this process, yet much remains to be done before patients can fully benefit from these modern approaches. Talents, ideas and expertise are much needed to overcome the challenges ahead. You are warmly invited to join the effort!

Department Seminar

On August th 18th Jaakko Peltonen will give a talk at the UIB Infromatikk Department Seminar, with the title "Lost in Publications? - How to Find Your Way in 50 Million Scientific Documents by Machine Learning and Interactive Intent Modelling".

Abstract
Before one can analyze relevant data one must first find it from among the huge amount of available data. The most common example is information seeking from large masses of documents, whether it is from the general web or from large collections. Often the search is exploratory, and it may be hard to formulate a good query, but traditional information retrieval systems do not sufficiently help users to improve unsatisfactory results. In this talk I discuss an improved system for exploratory search, where users are given power to direct their search by interacting visually with a model of their search intent. My talk concentrates on a particular domain: information seeking of scientific documents. Finding relevant documents is a common task for researchers, who must navigate big data to keep up to date with ongoing research and place their own work in context. Current scientific knowledge includes more than 50 million published articles -- among such a huge mass of data, how can a system help a researcher find relevant documents in their field? We introduce SciNet, an interactive search system that anticipates the user’s search intents by estimating them from the user’s interaction with the interface. The estimated intents are visualized on an intent radar, a radial layout that organizes potential intents as directions in the information space. The system assists users to direct their search by allowing feedback to be targeted on keywords representing the potential intents. Users can provide feedback by moving the keywords on the intent radar. The system then learns and visualizes improved estimates and corresponding documents. The resulting user models are explicit open user models curated by the user during the interactive information seeking. SciNet has been shown to significantly improve users’ task performance and the quality of retrieved information without compromising task execution time. We also show how user models learned in SciNet can be used to help cold-start recommendation in another system, the CoMeT talk management system, by cross-system user model transfer across the systems.

VCF on August the 12th

On August th 12th Paul Rosenthal will give a talk at VCF, with the title "Reproducibility in Visual Computing".

Abstract
Reproducibility is the basis of all sciences. Without reproducibility, there is no advancement by building on previous knowledge and there can be no judgment of the reliability of current knowledge. As all fields of visual computing have matured, procedures for verifying and evaluating techniques have been introduced also in these field. While many individuals are making their code and procedures available, there are no established guidelines for reproducibility in the communities. However, introducing such practices would increase the acceptance of visual computing methods in other communities, make contributions more well-grounded, and expedite future innovation by making comparisons and improvements easier. In this talk, I will discuss this important role and the benefits of a strong culture of reproducibility. The explanations will be carried out with special focus on the fields of visualization, human-computer interaction, and computer graphics. Still, they can be transferred to other disciplines in many aspects and stimulate the respective discussion there.

VCF on May the 27nd

On May 27nd Erik Hanson will give a talk at VCF, with the title "Perfusion modeling - The link between reservoir simulation and medical compartment modeling".

Abstract
Perfusion, the amount of blood feeding a volume of tissue, has for decades been possible to measure using medical imaging techniques and simple mathematical models. The imaging technology and the mathematical and numerical tools needed to solve the models have evolved rapidly over this period. At the same time, the models themselves have not changed accordingly. In this talk we will se how methods for modeling of porous media flow may contribute to a better mathematical understanding of perfusion modeling. The pressure driven flow trough a capillary system is an essential concept both in perfusion and reservoir/porous media simulation. We will discuss how this link may contribute to an improved modeling framework suited to make use of the extensive amount of information accessible through modern 4D medical imaging.

VCF on April the 22nd

On April 22nd Bjørn Tore Gjertsen will give a talk at VCF, with the title " Untangling intracellular signaling network in cancer".

Abstract
Protein and gene networks centered on the regulatory tumor suppressor proteins may be of crucial importance both in carcinogenesis and in the response to chemotherapy. Tumor suppressor protein p53 integrates intracellular data in stress responses, receiving signals and translating these into differential gene expression. Interpretation of the data integrated on p53 may therefore reveal the response to therapy in cancer. Proteomics offers more specific data – closer to “the real action” – than the hitherto more frequently used gene expression profiling.
We are currently working with single cell immune profiles that include information about intracellular signaling systems. Patient cancer cells are sampled before and under therapy to determine response or therapy failure as early as possible, thereby adjusting therapy to the benefit of the patient. Data visualization tools have been imperative for our interpretation of measurements. The question open for discussion is if we need better data visualization tools to easy grasp the dynamics of cancer, and if we have these tools available for visualization with exponentially increasing data density.

On February 19th Rasmus Slaattelid will give a talk at VCF, with the title " Visualization, story telling, and the big picture".

Abstract
At the University of Bergen, there exists several research environments that focus on visualizations. Visualizations of data, or of scientific knowledge more generally, visual cultures, diagrammatic thinking, and story-telling in visual media. If we look beyond the UoB, the picture grows even more diverse. This multitude of approaches and interests already suggests that a comprehensive understanding of visualization as a cognitive tool within one discipline is difficult, and that more collaboration across these disciplinary divides would be fruitful. The aim of my talk is to present some possible common areas of interest between different disciplines studying visualizations.

VCF on October the 16th

On October 16th Junyong You will give a talk at VCF, with the title "Perceived visual quality assessment".

Abstract
Visual signals are often distorted due to unavoidable factors, e.g., lossy compression, transmission over error prone networks. Accurate assessment of visual quality plays an important role in multimedia services in order to provide the best viewing experience to end-users. Traditionally used quality metrics, e.g., PSNR (peak signal-to-noise ratio) often cannot accurately represent the actual distortions perceived by human users. For example, the distorted images below all have same PSNR values with respect to the original reference image, while they present different levels of perceived distortions. This talk presents methodologies of perceived visual quality assessment, including visual mechanism modelling and applications in objective visual quality metrics. A video quality metric driven visual attention and foveation mechanism that was developed by the presenter will be introduced as an example. Applications in other areas will also be briefly mentioned.

Understanding their function helps to reveal the fundamentals of biochemical processes that are taking place in living cells. This search process, however, consumes an enormous amount of time and resources, due to the internal protein dynamics, which constantly change structural and biochemical characteristics of the protein over time. Thus, several in-silico predictive methods already appeared, which focus mostly on the analysis of the protein structure. In this talk we will mainly focus on methods for interactive exploration of protein inner void space including its geometry, physico chemical properties and dynamics to evaluate or modify the reactivity of the protein with other small molecules.

VCF on August the 28th

On August 28th Ivan Viola will give a talk at VCF, with the title "Bridging Spatial and Temporal Scales in Biological Data Visualization".

Abstract
"The study of biological processes carried out in living organisms is among the central foci of modern science. The field is nowadays by large extent computational, there are many kinds of digital models that characterize particular aspects of life. To provide a comprehensive view on biological phenomena, visualization offers itself for integrating multiple models into one visual environment. One of the interesting challenges, associated with such a visual integration, is to communicate phenomena that are simultaneously described on several spatial and temporal scales. In my talk I will discuss visualization techniques that bridge five orders of magnitude of spatial scale by interactively displaying structural information from a single atom level up to entire bacteria cell size with complete molecular machinery When dealing with simulation of molecular interactions in living organisms, agent-based models are used to model long sequences of Brownian motion that randomly carry out several physiologically relevant events. One such event occurs on average every thousandth simulation iteration in the agent based simulation. In order to perceive random motion but also to see relevant events simultaneously, we bridge two temporal scales that are three orders of magnitude apart from each other. The approach is based on a special timelapse approach inspired from scientific animation techniques. In the last part of my talk I will present a technique for interactive 3D visualization of molecular reaction pathways that is controlled in a top-down manner by quantitative simulation and is simultaneously covisualized. In such visual environment the viewer can interactively control the visualization as well as simulation parameters."

VCF on May the 21st

On May 21st Lars Linsen will gave a talk at VCF/UIB depatpent seminar, with the title "Visual Analysis of Ensembe Simulations".

Abstract
Mathematical models are used for the description and the understanding of phenomena in all sciences. Numerical simulations support the validation of the models and data assimilation purposes. Such simulations often depend on a number of simulation parameters and initial configurations. The selection of these parameters and configurations is often not exactly known or their impact is part of the underlying research tasks. Therefore, multiple simulation runs with varying parameter settings or ensembles of simulations with varying configurations are executed. The analysis of such simulation ensembles is complex, especially when each simulation run represents a four-dimensional spatio-temporal phenomenon. The amount of data of a simulation ensemble often adds up to hundreds of Gigabytes or even Terabytes. The analysis of such complex data is no longer possible without the use of computers. On the other hand, such an analysis typically requires the expertise of a human. As visual representations are intuitive and can be processed efficiently by humans, it is a suitable approach to combine visual representations and interaction mechanisms with automatic analysis steps. In this talk, I will present novel visualization methods that allow for an interactive comparative analysis of such large and complex data stemming from simulation ensembles. The methods are applied for the analysis of data stemming from biology, climate research, astrophysics, and medicine.

VCF on February the 6th

On Febraury 6th Erlend Hodneland gave a talk at VCF, with the title "Quantitative analysis of dynamic contrast enhanced MR (DCE-MRI) data of the kidney".

Abstract
"Quantitative analysis of DCE-MRI data from the kidney has the potential to become a clinically highly useful imaging modality for the non-invasive investigation of organ function. There are major challenges related to perfusion imaging of the human kidney that I want to address. The processing pipeline has several components: choice of MR sequence, breathing pattern, conversion to tracer concentrations, motion correction, segmentation of kidney and arterial input function (AIF), and compartment modelling for estimating the filtration and perfusion. The reproducibility between repeated MR scans is high, but a comparison to clinical standards for kidney filtration reveals that the MR estimates for filtration are still not within the range for active clinical use. In this presentation I will address the challenges related to the processing pipeline."

Title: Illustrative 3D visualization of seismic data
Supervisors: Helwig Hauser and Daniel Patel
Sensor: Dag Magne Ulvang
Time: Friday, Oct. 11, starting at 9.00am
Place: room 2103 (1st floor, data blokk, Høyteknologisenteret)
Abstract:
Seismic datasets are usually large and noisy, with no apparent structures, at least to the untrained eye. Geo-illustrators and geologist use a set of 2D textures, lithological patterns, to show the interpreted information in seismic data. Lithological patterns are illustrations of the contents of a rock unit or a rock formation. For 2D slice viewing, and for 2D planar cuts in a 3D object, a 2D texture is sufficient.
But to fully take advantage of the information found in 3D seismic datasets, we want to explore the use of specially designed 3D textures to show the interpreted information. This opens up some new possibilities, such as viewing the interior of the seismic volume, by using traditional tools for handling of occlusion. Unfortunately, no such 3D lithological textures exists.
This thesis deal with the process of creating the 3D textures. We analyse and break the 2D lithological patterns down into symbols and their integration. Then each 2D symbol is manually extended to its plausible 3D counterpart, and finally the 3D objects are placed in the texture as de ned by its integration. The control over this synthesis process is placed in a XML schema for flexibility. The lithological patterns covers a variety of di erent textures from stochastic such as sand to the structural limestone, and thus follows the two main types of textures that we are able to create, structured textures and stochastic textures.

Title: Selected Opportunities for the Semiautomatic Analysis of Spectrally Decomposed Seismic Data
Abstract: Seismic imaging/visualization of the subterranean is an important part in the process of identifying and extracting hydrocarbons such as oil and gas. One promising method that is used to assist in visualizing seismic reflection data is spectral decomposition. Spectral decomposition is a contrast enhancing technique that helps in identifying subterranean features. This thesis presents a set of new opportunities for visualizing spectrally decomposed seismic based on techniques known from visualization and image Segmentation. In particular it focuses on presenting a new technique based on Interactive Visual Analysis (IVA) and feature extraction based image segmentation. In addition to the visualization and segmentation techniques, pre-processing steps for making the data more suitable for visualization are suggested. Some of the pre-processing techniques are well known from the image processing field. Time: Friday, August 23, 2013, 08h45
Place: room 2143, Høyteknologisenteret, floor 2
The thesis was supervised by professor Helwig Hauser. The sensor will be Dr. Armin Pobitzer from Christian Michelsen Research.

New Visualization Master: Morten Bendiksen !


Congratulation to our student Morten Bendiksen, who succesfully defended his M.Sc. thesis entitled Rapid Modeling of Geology .
Abstract: "Drawing three dimensional models of geological phenomena is today a process requiring training in specific programs that can be very time consuming. For illustration and communication of geological concepts, geologists therefore often limit themselves to drawing on paper or to two dimensional drawing applications. In this thesis I propose an approach for making rapid geologic illustrations in 3D. The novel idea for the approach consists of sketch based input on a cube in order to create a layered geological structure. Further details can be added to the layers by sketching geological concepts such as rivers, mountains and valleys. Sedimentary deposits can be created through a procedural modeling approach that employs a volume preserving diffusion algorithm to simulate the flow of depositional material on top of the terrain. Awareness of the geologic domain enables a sparse amount of input strokes to be interpreted into geological structures. Results show that the proposed approach can be used with success to model geological layers. Compared with a 2D sketch, the creation of a 3D geometry on a computer gives advantages such as perspective control, ease of making changes to the model, etc. The approach shows great promise and can be useful in many situations. A program based on the proposed approach could become a standard way for geologists to draw their illustrations."

New Visualization Master: Stian Sivertsen !


Congratulation to our student Stian Sivertsen, who succesfully defended his M.Sc. thesis entitled Ridge Extraction, and Illustrative Visualization of an FTLE Flow Field .
Abstract: "Illustrative visualization of a flow is an area that is proving to be interesting and in later years something that have been somewhat explored, it can provide some very interesting results and in this thesis we find the required structures needed for such a visualization. Lagrangian coherent structures are now commonly used in flow visualization and we establish a simplistic approach to creating them in this thesis. The problem of occlusion and the general complexity of both the data and the visual results are still a common thing when working with a structured flow. This thesis presents a solution that identifies the complex and often large amounts of data that is inherent in a flow and tries to find a good way of extracting the structures within. By using the FTLE values found in the flow data we define these structures so that we can see what is going on in these complex systems, as well as combining it with an illustrative approach that will provide an interesting visual aspect to the integral structures found in flows. By using mathematical analysis of the raw data we obtain the necessary tools we need to define and extract ridges that form LCS that we can then model.We use a simple approach by focusing on the basic components of such complex structures as well as utilizing often long standing principles in an interesting way. Combining the strengths of both illustrative visualization and the clarity of integral structures we can create a more visual sound model that loses some of its cluttering complexities but is still capable of generating a pleasing visual end result."

Congratulation to our student Sondre Hisdal, who succesfully defended his M.Sc. thesis entitled Frequency Modulated Shading .
Abstract: "In this thesis we describe a frequency modulated shading technique. The goal is to improve the visualization of 3D ultrasound data by combining depth cues from shadows, and structural information from gradient-based shading. The computation of gradients suffer from noise, and since ultrasound data has a low signalto- noise ration straight forward gradient computation gives poor results. To improve the gradient-based shading we use frequency modulation to get smoothed gradient. The technique performs a local area analysis for each voxel in the volume. The analysis creates a local subvolume around the voxel currently being investigated. This subvolume is transformed into frequency domain, where some frequencies are filtered out. The filtered volume is transformed back into spatial domain, where it is used to compute gradients. The filtered gradients are then used in combination with a shadow renderer, to provide both gradient based shading and shadows."

New Visualization Master: Kari Ringdal !


We congratulate our student Kari Ringdal who has successfully defended her M.Sc. thesis entitled Flow-based Segmentation of Seismic Data.
Abstract: "This thesis presents an image processing method for identifying separation layers in seismic 3D reflection volumes. This is done by applying techniques from flow visualization and using GPU acceleration. In geology sound waves are used for exploring the earth beneath the surface. The resulting seismic reflection data gives us a representation of sedimentary rocks. Analyzing sedimentary rocks and their layering can reveal major historical events, such as earth crust movement, climate change or evolutionary change. Sedimentary rocks arc also important as a source of natural resources like coal, fossil fuels, drinking water and ores. The first step in analyzing seismic reflection data is to find the borders between sedimentary units that originated at different times. This thesis presents a technique for detecting separating borders in 3D seismic data. Layers belonging to different units can not always be detected by looking in a local neighborhood. Our presented technique avoids the shortcoming of existing methods that work on a local scale by addressing the data globally. We utilize methods from the fields of flow visualization and image processing. We describe a border detection algorithm, as well as a general programming pipeline for preprocessing the data on the graphics card. Our GPU processing supports fast filtering of the data and a real-time update of the viewed volume slice when parameters are adjusted."

NFR Evaluation !


Every 10 years, Norway's Research Council is organizing an evaluation of all research groups in informatics in Norway, which is worked out by an international board of experts. Being still relatively young, the visualization research group in Bergen was now evaluated for the first time. In total, 62 research groups were evaluated. Five of them received the best possible grade (5) and we are proud that two of them are also from the Dept. of Informatics in Bergen. The VisGroup Bergen was rated 4-5 which places it amongst the top-15% of all informatics research groups in the country -- a good start, as we think! :-)
The full evaluation can be found here.

Very successful EuroVis 2011 in Bergen


With satisfaction we are looking back at a very successful EuroVis 2011, which was highly appreciated by its participants.  It is notable that new dimensions were conquered with this year's EuroVis:  never ever more participants joined (we recorded an up of about 15% compared to 2009 and 2010) ;  no other high-quality conference on visualization (world-wide) received more submissions than EuroVis 2011;  and more than half of the (significantly larger than ever) conference budget was covered by supporters and sponsors. Many reasons, actually, to be very glad to having had EuroVis 2011 in Bergen!  Questions to Helwig Hauser or Ivan Viola.
