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.
图像压缩的模内相关编码方法
基于H.264/AVC的无损图像压缩是一种最新、最广泛的数据压缩技术。基于块的内部预测最初在这个扩展中被利用。基于DPCM的内预测是该研究领域提高压缩比的一种优秀技术。为了进一步提高基于dpcm的压缩技术的性能,本文提出了一种模式内相关的编码方案。在对不同的内模进行预测后,在熵编码之前考虑不同的扫描顺序来拟合不同的数据属性。
