- 运动估计是视频编码的关键技术,其最基本的原理是利用相邻帧间的时间 相关性,通过预测来减少时间冗余度。在实际编码中,为了节省码率,并不传 输每一帧的全部数据,而是利用运动估计求出每一帧与其预测参考帧之间的差 值。运动估计越准确,差值的分布越趋近与零,差值块的能量越小,经过变换、 量化和熵编码后所产生的码流的比特位率也越少。因此,运动估计搜索的准确 程度直接影响到了编码的压缩性能。 -Motion estimation is the key to video encodin

- 视频信号熵编码源程序 熵编码法是一种进行无损数据压缩的技术,在这个技术中一段文字中的每个字母被一段不同长度的比特(Bit)所代替。与此相对的是LZ77或者LZ78等数据压缩方法,在这些方法中原文的一段字母列被其它字母取代。 每个字母按照其出现的可能性所获得的最佳比特数取决于熵。 本程序不仅提供源程序,还提供相应的实例。-Entropy coding the video signal source for entropy coding method is a lossless data
