NSCT非下采样Contourlet变换，实现对图像的多尺度多方向分解，是一种真正的二维图像表示方法-NSCT nonsubsampled Contourlet transform, to achieve multi-scale multi-orientation image decomposition, is a true two-dimensional image representation

基非下采样的Contourlet变换的图像融合，要放到NSCT工具包中执行-Under the base of non-sampling Contourlet transform image fusion, to put the implementation of the toolkit NSCT
