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 transforms 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...
In this paper we propose the use of intra-frame prediction with lapped transforms for image coding. Both lapped transforms and intra prediction exploit the redundancies of neighboring blocks and the combination of the two techniques results in a very efficient image coding scheme. The difficulty to combine them comes from the necessity to use for the prediction of the current block pixels in the causal...
