Paper Abstract:
|
This paper presents a novel framework for scalable video coding. The proposed paradigm combines open-loop motion-compensated temporal filtering (MCTF) with an embedded inter-band wavelet based compression. The latter extends Set Partitioning in Hierarchical Trees (SPIHT) algorithm to video sequences. Our major objective is to provide a simple and fast wavelet based video coding system that circumvents the drawbacks of conventional closed-loop prediction systems. To improve the compression performances, the target bitrate is weighted adaptively according to the temporal frame position in the temporal pyramid. Experimental results show that the performance and complexity of our video coder compare favorably with the existing state-of-the-art scalable video coders. |
