Abstract :
This paper propose the use of lapped transforms in a predictive video coding scheme. Our approach involves an inter-frame, block-based prediction based on lapped trans forms and allows rate-distortion optimization, different block sizes and integration with intra-frame prediction. Moreover, this coding scheme strongly reduces the blocking artifacts associated to block-based transforms and permits a better exploitation of the redundancies beyond block borders. The proposed method presents promising results in comparison to the standard implementation of the H.264/AVC, especially for high-definition sequences.
