It has been widely believed that motion-compensated update steps performed in the motion-compensated temporal filtering (MCTF) framework improve coding efficiency in comparison to conventional hybrid coding. However, the coding efficiency of MCTF update steps for scalable video coding has not been examined sufficiently in the past. In this paper, we investigate the efficiency of the decoder side update...
This paper presents a theoretical model and study of the impact of the weighted motion-compensated residual energy on the coding efficiency of motion-compensated temporal filtering (MCTF) when MCTF update steps are performed at both encoder and decoder sides and when update steps are executed at the encoder side only. We observe that in the presence of the uncompensated quantization errors due to...
In this paper, we present a content-adaptive chrominance and motion vector correlation-based update step for scalable video coding. It takes advantage of the chrominance information in the video sequence and the correlation of motion vectors (MVs) of the neighboring blocks as well as the correlation of the derived update MVs in the low-pass frames to improve the update step of lifting-based motion-compensated...
