The fifth chapter use huffman coding method of the row difference data and lifting wavelet transform and spiht ( set partitioning in hierarchical tree ) coding method to realize the diagnostically compression of mfl data by judging the significance of data using changing threshold and dynamic area threshold of mfl data
在第五章通过数据变化阈值和数据动态范围阈值判断数据重要性，分别采用行差分数据的霍夫曼编码方法以及提升小波变换和层次树集分割( spiht )编码方法实现了数据的检测无损压缩。
