A filter bank structure that can deal effectively with piecewise smooth images with smooth contours, was proposed by Minh N Do and Martin Vetterli. The resulting image expansion is a directional multiresolution analysis framework composed of contour segments, and thus is named contourlet. This will overcome the challenges of wavelet and curvelet transform. Contourlet transform is a double filter bank structure. It is implemented by the pyramidal directional filter bank (PDFB) which decomposes images into directional subbands at multiple scales. In terms of structure the contourlet transform is a cascade of a Laplacian Pyramid and a directional filter bank. In essence, it first use a wavelet-like transform for edge detection, and then a local directional transform for contour segment detection. The contourlet transform provides a sparse representation for two-dimensional piecewise smooth signals that resemble images.

本文中有两个函数m文件:model126.m是一个用于预测的完全没有用工具箱函数的补偿模糊神经网络主程序,用于仿真、对比训练数据和网络输出的差异;cb.m是一个非线性系统的数学模型,在model126.m中用“ode45”函数求解这个数学模型后,可以得到105个x1(t)、x2(t)和y(t),从而建立起一个两输入一输出的补偿模糊神经网络。(failed to translate)
