Segmentation and 2-D motion estimation of noisy image sequences

Two of the most important problems in scene analysis of image sequences are the segmentation of image frames into moving and nonmoving components and the 2-D motion estimation of the moving parts of the scene. The algorithm has two parts: segmentation and 2-D motion estimation. These two parts are interactively connected in a mutually beneficial way. The authors concentrate on the 2-D motion estimation problem assuming that the segmentation has been performed. Two algorithms for 2-D motion estimation are presented. The first is based on the method of differentials, while the second is a boundary matching method.<
