- 本文提出了一种基于独立分量分析的音频数字水印方法。嵌入水印时,对原始音频文件进行一级小波分解,在分解 得到的逼近分量中利用随机混合方法嵌入水印后进行小波逆变换形成嵌入水印的音频文件。仿真实验结果表明这种方 法的强鲁棒性和可行性。-Abstract:Audio p roduction is one of the important digital multimedias, which transmit becomes more and more convenient. To p rev

- 单层小波变换对二维图像进行分解,[cA1,cH1,cV1,cD1]=dwt2(X, db1 ):计算图像X指定小波基的单层二维离散小波变换分解，其中cA为近似小波系数矩阵，参量cH,cV和cD分别为小波分解的水平细节系数、垂直细节系数和对角细节系数。-Single layer wavelet transform to the two-dimensional image decomposition, [cA1, cH1, cV1, cD1]=dwt2 (X, db1 ): X single ima

- 使用维单尺度离散小波变换，通过迭代进行对低频进行单尺度离散小波分解，也可以达到对原图像进行多尺度分解的目的。而且若使用二维单尺度离散小波变换，各个系数的提取以及单支重构都有matlab现成的函数，很容易进行操作。唯一存在的问题是当避开二维多尺度离散变换函数，试图利用二维单尺度离散小波变换函数dwt2对每次分解后得到的低频系数不断进行处理时，在某些小波基的情况下会造成重构的失败。-Using the dimension discrete wavelet transform, the discret
