Abstract:
This paper presents a new video segmentation scheme for object-oriented MPEG-4 video coding. In the scheme, the object motion is modeled by quadratic transform with coefficients estimated via a nonlinear Quasi-Newton method. To effectively merge the regions with similar motions within an image, a region merging process, which is guided by a weighted region adjacency graph, is employed. Simulation results show the proposed scheme provides high performance in terms of segmentation accuracy and video compression ratio.
