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。

首先将二值水印图像经过降维操作转化为一维序列,再将一维序列与m 序列做扩频
调制,最后对音频信号进行分段离散余弦变换,把经过调制的水印信号经过量化处理过程嵌入到离
散余弦变换后的系数中 提取水印时对含水印信号的音频信号也进行分段离散余弦变换,然后利用
原始音频信号提取水印. 实验证明了该技术的鲁棒性和不可感知性.
