Abstract

Motion estimation is an important aspect for image sequence analysis, which is part of image sequence coding. Due to its simplicity and robustness the currently preferred motion estimation technique is block matching. The approach described in this paper eliminates the systematic limitations of conventional block matching. The algorithm is based on a resolution pyramid which is treated as a tree with one to one relationships (links) of the pixels between the levels. Within the pyramid motion estimation is done top-down by matching each pixel, which results in a multiresolution motion vector field. The links are iteratively refined according to a homogeneity criterion incorporating the intensity as well as the motion vectors. Hence a segmentation of the image is obtained and motion estimation is performed on regions instead of blocks. Motion estimation and segmentation are performed iteratively in alternating steps. The final segmentation obtained is characterized by homogeneous motion as well as homogeneous intensity.
