Abstract: In this paper, a new methodology for optical flow estimation that is able to represent multiple motions is presented. To separate motions at the same location, a new frequency-domain approach is used. This model, based on a band-pass filtering with a set of logGabor spatio-temporal filters, groups together filter responses with continuity in its motion (each group will define a motion pattern). Given a motion pattern, the gradient constraints is applied to the output of each filter in order to... (Update)
