JPEG图像压缩和解压MATLAB程序，使用了DCT2、线性量化编码、zigzag变换和游程编码理论-JPEG image compression and decompression MATLAB procedures, using DCT2, linear quantization coding, zigzag transform and run-length coding theory

本实验要求编写一个计算压缩-解压缩图像的均方根误差、均方信噪比的程序。该程序是一个通用程序。编写程序产生图示的结果。使用上面的保真度准则程序计算可视信息的损失特性。-Prepared in this experiment, a calculation of compression- decompression of the root-mean-square error of image, mean square signal to noise ratio of the procedure. Th

for using this code need to use signal toolbox and general toolbox in your matlab Using Daubechies transform to compress the image (showing remaining coefficen of Thresholded Image) and then using Inverse 2D Daubechies transform and finding t
