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

these codes read input image and generate the 2D gabor filters, with changeable scale, orientation, perform the convolution with input image.

基于MATLAB的车牌图像分割（定位，预处理，分割，识别）-License plate image segmentation based on MATLAB (orientation, preprocessing, segmentation, recognition)

Useful tool for rendering and outputting information rich images-This function can be used in place of IMAGE, IMAGESC and IMSHOW, but does so much more. It is fast and displays images as they should be- correct aspect ratio, integer magnification, no
