小波分析\小波构造,小波 分析\小波构造-Wavelet Wavelet analysis, Wavelet analysis Wavelet

对图像进行压缩感知，通过构造小波正交变换矩阵进行稀疏表示，用OMP重构-CS of image based on WT

先对信号进行提升小波分解，然后构造传统小波分解结构[c,l]；接着使用函数ddencmp获取信后压缩阈值，最后采用函数wdencmp实现信后压缩。-First signal lifting wavelet decomposition, and then construct the traditional wavelet decomposition structure [c, l] then use the function to get the letter ddencmp compressi

基于CS的图像压缩解压，包括CoSaMP和OMP恢复算法，离散小波变换矩阵构造，具体对图像进行压缩解压-CS-based image compression and decompression, including CoSaMP and OMP recovery algorithms, discrete wavelet transform matrix structure, specifically for image compression and decompression
