A Contrast Invariant Approach to Motion Estimation

Abstract. Motion estimation is one of the key tools in many video processing applications. Most of the existing motion estimation approaches use the brightness constancy assumption in order to model the movements of the objects present in the scene. In this paper the motion of objects is modeled from a geometrical-based point of view, leading thus to a contrast invariant formulation. The present approach is region-based and assumes affine motion model for each region.
