AbstractRecent advances in computing and simulation technology promote the simulation of
time-dependent flows, i.e., flows where the velocity field changes over time. The simulation
of time-dependent flow is a more realistic approximation of natural phenomena and it
represents an invaluable tool for scientists and practitioners in multiple disciplines,
including meteorology, vehicle design, and medicine. Flow visualization, a subfield of
scientific visualization, is one of several research areas which deal with the analysis of
flows. There are many methods for the analysis of steady flows, but the extension to the
time-dependent case is not straight forward. The SemSeg project, a FET-Open project in the
7th Framework programme, attempts to provide a solution for the semantic segmentation of
time-dependent flows. It aims at the formulation of a sound theoretical mechanism to describe
structural features in time-dependent flow. In this paper, we briefly summarize recent
research results from the SemSeg project. Several different approaches are pursued in
the project, including methods based on the finite-time Lyapunov exponent (FTLE), methods based
on vector field topology (VFT), and interactive visual analysis (IVA) methods. Uncertainty
visualization and the interactive evaluation of methods are helping in evaluating the results.
