一种新的Contoutlet变换，它具有明显频率局部性。上传的是这种新算法的工具箱。-a new Contoutlet transform, it is apparent frequency localized. Upload the new algorithm toolbox.

实现一种小波变换是一种常用的变换，对初次使用小波变换的很有用。-realise a wavelet transform and it is very useful.

第二代Contourlet工具包，处理去噪，压缩，分割效果很好，是应用的热点。Matlab语言的-Contourlet Kit second generation, processing denoising, compression, segmentation works well, is the application of the hot spots. Matlab language
