在对原图像进行双正交7／9三级小波分解后 ，在第二级的水平、垂直、对角以及第三级对角分量上加入水印系数，再经过小波反变换重构出图像。-in the original image Biorthogonal 7 / 9 3 wavelet decomposition, in the second-class level, vertical, diagonal, and the third-class right angle to add weight coefficient watermark, a

MATLAB实现声音信号的小波分解与重构内副数据 不错的-MATLAB voice signal wavelet decomposition and reconstruction of the pair of data is good

在matlab仿真平台上对某一心音信号进行采样、小波分解、消噪处理、信号重构等信号处理(Heart audio data processing)

对信号波形进行小波变换并分解，提取模极大值，最后进行信号重构。(Wavelet transform and decompose the signal waveform, extract the maximum value of the modulus, and finally reconstruct the signal.)
