Contourlet变换的实现源码。相关理论可参考:Do M N, Vetterli M. \"The contourlet transform: an efficient directional multiresolution image representation\" [J]. Image Processing, IEEE Transactions on, 2005, 14 (12): 2091-2106.

有关图像信号处理的有关MATLAB源代码，包含的对含噪声图像的消噪过程，用以图像的恢复-The image signal processing on MATLAB source code, contains an image containing noise denoising process for image restoration

这是一个图像增强的应该实例，首先画出原始图像，下来进行图像的增强处理，用sym4小波对x进行2层小波分解，对处理后的系数进行重构，最后画出重构图像。-This is an instance of image enhancement should first draw the original image, down to the image enhancement processing, with sym4 x for 2-layer wavelet wavelet decomposition,
