A drift compensation architecture for DCT-pyramid video coding
International Symposium on VIPromCom Video/Image Processing and Multimedia Communications - Trang 315-318
Tóm tắt
A new-layered video coding scheme is proposed for efficient spatial scalability based on the DCT pyramid. The proposed scheme is introduced to eliminate the drift error associated with reduced resolution video. A new algorithm to predict the motion vector of the reduced resolution video from the higher resolution motion vectors is presented. Based on simulation results, the proposed scheme achieves better coding efficiency and lower complexity than H.263+ spatial scalability.
