Title: More with less: exploiting structure in directional-field processing.
Abstract: Directional fields comprise sets of vectors on surfaces and in volumes, where they are prominent objects of geometry processing. They represent flow, movement, trajectory, or alignment. Traditional methods to compute and analyze fields are flawed in several aspects: they are computationally expensive even though the fields might be very smooth, they result in noisy solutions on coarsely-sampled domains, and they do not respect the topological structure of such fields: sinks, vortices, singularities, flow lines, and more. I will discuss a few of my recent methods that make the most out of structure and low-dimensionality in directional fields, leading to robust and accurate computations.
