Abstract. We use a simple yet powerful higher-order conditional random field (CRF) to model optical flow. It consists of a standard photoconsistency cost and a prior on affine mo...

A spatio-temporal representation for complex optical flow events is developed that generalizes traditional parameterized motion models (e.g. affine). These generative spatio-tempo...

Abstract. This paper de nes a temporal continuity constraint that expresses assumptions about the evolution of 2D image velocity, or optical ow, over a sequence of images. Temporal...
