matlab环境下利用huffman编码实现图像无损压缩和文本的压缩-matlab environment implementation using huffman coding image lossless compression and text compression

implementation approach for the compression of image data for lossless image compression saved in lower resolution and are retrieved with super resolution

使用游程编码对二值图进行压缩和解压，适合学习，注释详细。 该编码属于无损压缩编码，是栅格数据压缩的重要编码方法。对于二值图有效。(This code belongs to lossless compression coding and is an important coding method for grid data compression. It is valid for the two value graph.)
