(English) Solving Motion Planes by Projection and Ring Integration
Abstract We present a new method to find motion planes in energy based and spatio-temporal derivative optical flow. Because our method makes few assumptions about the motion model and the number of motions present in the sampling window, we are … Continue reading

(English) MRF solutions for probabilistic optical flow formulations
Abstract In this paper we propose an efficient, non-iterative method for estimating optical flow. We develop a probabilistic framework that is appropriate for describing the inherent uncertainty in the brightness constraint due to errors in image derivative computation. We separate … Continue reading
