Abstract :
A novel algorithm for coding gray level alpha planes in object-based video is presented. The scheme is based on segmentation in multiple layers. Different coders are specifically designed for each layer. In order to reduce the bit rate, cross-layer redundancies as well as temporal correlation are exploited. Coding results show the superior efficiency of the proposed scheme compared with MPEG-4
