实现jpeg压缩和解压缩,将彩色图像进行颜色空间转换、对不同的颜色分量进行不同的采样、对于3个分量进行8×8的DCT变换、对DCT系数矩阵按照JPEG推荐的量化表进行量化;对量化后的系数进行Z形扫描,最后进行熵编码,形成码流,计算比特数,和压缩比。解压从量化后的DCT系数表开始逆向进行-Jpeg compression and decompression, the color image is a color space conversion, the different color components of different samples for the three components of 88 DCT, DCT coefficient quantization matrix according to the recommended JPEG quantization table right quantized coefficients Z-scan and finally entropy encoded to form a code stream, calculating the number of bits, and compression ratio. Extracting from the quantized DCT coefficients reverse the tables begin
