matlab 实现游程编码（RLE）的压缩编码和解码， 对于二值图像具有很好的效果。自己做的作业，可以用-matlab run-length encoding (RLE) compression encoding and decoding, and has a good effect for the binary image. Their own job to do, can be used

) Compression using huffman code -with a number of bits k per code word -provide huffman table Huffman coding is optimal for a symbol-by-symbol coding with a known input probability distribution.This technique uses a variable-length code t
