Abstract

This paper presents a new video coding structure for application in videophone and videoconferencing systems. The new structure utilizes image segmentation by quadtree decomposition in the motion estimation and compensation stages. A significant reduction in computational effort is achieved, as compared to conventional structure. The new scheme leads to a high objective image quality for operation at low bit rates. Computer simulations are presented which compare the new structure and a coder based on the H.261 standard for performance. The results obtained demonstrate the effectiveness of the new coding scheme.
