图像孔洞/裂缝的填充算法。根据图像的同态性，采用最邻近插值的思想。(Image holes/cracks in the fill algorithm. According to the image of the same state, using the nearest interpolation ideas.)

Image Filtering RGB Spatial Wiener Direct Inverse Discrete Fourier Transform DFT Lucy Richardson Median Laplacian (Image Filtering RGB Direct Spatial Wiener Inverse Discrete Fourier Transform DFT Lucy Ri chardson Median Laplacian)

一个基于脉冲耦合神经网络的高斯噪声滤波程序，包括源码和实验结果(pulse coupling based on a neural network Gaussian noise filtering procedures, including source and experimental results)

sift特征点检测及匹配，matlab源码(sift feature point detection and matching, matlab source code)

说明：  图像分割代码，c++实现(Image segmentation code, c++ Achieve)

说明：  为图像分别加高斯噪声和椒盐噪声，采用中值滤波方法对受噪声干扰的图像滤波，窗口分别采用3*3,5*5,7*7；(Gaussian noise and salt and pepper noise are added to the image respectively. The median filtering method is used to filter the image disturbed by noise. The window is 3 * 3,5 * 5,7 * 7;)
