DCTJPEG
blkproc.m,DCHuffmanEncoding.m,ACHuffmanEncoding.m,zigzag.m,PSNR.m,
对灰度图像进行DCT变换,量化,ZigZag扫描,Huffman编解码,反量化,反DCT变换而重建图像。
其中,blkproc.m为分块DCT变换函数;
DCHuffmanEncoding.m,ACHuffmanEncoding.m分别为DC和AC变换系数的Huffman码表函数;
zigzag.m为ZigZag扫描函数;PSNR.m为求图像峰值信噪比函数。

jpg_encoder_and_decoder_matlab
自己用matlab写的灰度图像压缩解压程序
jpegencoder可以打开图像压缩后存储为c.jpg(只限于灰度图像)
jpegdecoder只适用于把jpegencoder的c.jpg解压,还不可以对任意图像解压,有待以后完善
