说明： 非下采样contourlet是超小波的一种。具有多尺度和多方向性，解决了contourlet变换无平移不变性的缺陷。用于图纹理特征提取和图像融合的效果很好。
(Non sampled contourlet is a kind of super wavelet. With multi-scale and multi directional, it solves the defect of Contourlet translation without translation invariance. For graph texture feature extraction and image fusion, the effect is very good.)

Nonsubsampled Contourlet Toolbox (version 1.0.0, August 2004)
This toolbox contains Matlab files that implement the nonsubsample contourlet transform and its utility functions. Some Matlab files are the same as those in Contourlet Toolbox.
The main functions are the following: nsctdec, nsctrec, n***bdec, n***brec.
+ nsctdec: Nonsubsampled contourlet decomposition.
+ nsctrec: Nonsubsampled contourlet reconstruction.
+ n***bdec: Nonsubsampled directional filter bank decomposition.
+ n***brec: Nonsubsampled directional filter bank reconstruction.
In addition, there are several demos (decdemo) that provide examples on how to use these functions.
Note: There are three mex file (zconv2.c, zconv2S.c, atrousc.c) in the nonsubsampled Contourlet Toolbox that might need to be recompiled.
This can be done by typing from the Matlab command window
>> mex zconv2D_O.c
