For example, the object is composed of four blocks, i.e. block A, B, C, D. Block A locates the left of block B and above block C. According to order, its code is ABDC etc. This code does not change its order after the object rotates, zoom, downsizes. The disadvantage of this method is that it will lose the target when the color is changed.A video fluid is composed of compressed data which include I, P and B(bi-prediction) frame. The data of each block of P frame is predicted by motion prediction and compensation from the data and motion vector of I frame.

This paper proposes a new EEG lossless compression technology based on improved DM Coding and Adaptive 2-Value Arithmetic Coding:First, DM Coding is used to the original data, and them through an appropriate transform of data format, most of the "redundant" bits in every byte are removed, also its Entropy of bits is reduced.

引言 多年来，嫡编码作为数据无损压缩的重要手段在生物医学信号的处理中一直得到广泛地应用，同时对于脑电信号的处理来说更是如此：由于神经疾病的诊断需要容量庞大的分析数据以及脑电波自身内涵的复杂性使得无损压缩对于脑电数据的处理而言异常重要；在另一方面，霍夫曼编码(Huffman Cod-ing)。
