Abstract :
H.264/AVC based lossless image compression is a latest and extent technique for data compression. Block based intra-prediction is originally exploited in this extension. DPCM based intra-prediction is an outstanding technique to improve the compression ratio for this research area. In this paper, we propose an intra-mode dependent coding scheme to further improve the performance of DPCM-based compression technique. Different scan orders prior to entropy coding is considered to fit the various data attributes after predictions for different intra-modes.
