a very handy code to compress color images using spiht algorithm with shape adaptive technique this version is been updated with some features of ROI

spiht算法处理24位彩色图像，可以选择小波变换层数和任意比压缩，对低比特流压缩实现优化-spiht algorithms dealing with 24-bit color images, you can choose wavelet transform layers and arbitrary than the compression, low bit-stream compression for optimal

使用分层树集合划分的压缩方法对彩色图像压缩并计算其均方误差和峰噪比-Using a hierarchical tree set partitioning compression method for color image compression and calculate the mean square error and peak-to-noise ratio
