ac_decode.m 对AC系数进行Huffman解码 ac_encode.m 对AC系数进行Huffman编码 bin2int.m 将二进制数转化成整数 dc_decode.m 对DC系数进行Huffman解码 dc_encode.m 对DC系数进行Huffman编码 dec2bit.m 将十进制数转换为制定位数的二进制码流 dez.m ZigZag扫描 divq.m 对输入矩阵进行量化 dpcm.m 差分预测编码 int2bin.m 将输入整数转换为二进制数 idivq.m 反量化 jpeg_decode.m 解码的可执行程序 jpeg_encode.m 编码的可执行程序 其中jpeg_encode.m和jpeg_decode.m分别是编码和解码的可执行程序。直接运行这两个程序就可以得到压缩比和峰值信噪比。可修改两个程序中的路径改变被压缩的照片。
