Abstract

{W}e consider a novel optic flow estimation algorithm based on a wavelet expansion of the velocity field. {I}n particular, we propose an efficient gradient-based estimation algorithm which naturally encompasses the estimation process into a multiresolution framework while avoiding most of the drawbacks common to this kind of hierarchical methods. {W}e then emphasize that the proposed methodology is well-suited to the practical implementation of high-order regularizations. {T}he powerfulness of the proposed algorithm and regularization schemes are finally assessed by simulation results on challenging image sequence of turbulent fluids.
