提出了一种基于预测编码的自适应无损视频压缩算法。该算法以一种反向自适应的方式利用时间、空间和频谱冗余，并具有极低的边信息。通过使用缓存策略，进一步降低了计算复杂度。我们还研究了编码器(小波或空间)的运算域与被编码序列中的时间和空间冗余量之间的关系。实验结果表明，该方案在压缩效率上有了显著的提高
We present an adaptive lossless video compression algorithm based on predictive coding. The proposed algorithm exploits temporal, spatial, and spectral redundancies in a backward adaptive fashion with extremely low side information. The computational complexity is further reduced by using a caching strategy. We also study the relationship between the operational domain for the coder (wavelet or spatial) and the amount of temporal and spatial redundancy in the sequence being encoded. Experimental results show that the proposed scheme provides significant improvements in compression efficiencies
