Optical Flow Estimation Using Discontinuity Conforming Filters

摘要

Discontinuities and large image displacements pose some of the hardest problems in flow estimation. This paper proposes a set of filters that change shape to avoid blending of the constraints across discontinuity boundaries according to an incompatibility measure of the constraints of neighboring pixels. The algorithm is embedded in a coarse to fine multigrid scheme to address the problem of large displacements. We report results on real and synthetic images which show that the algorithm works very well.
