先对图片进行灰度处理，然后进行高斯滤波，最后得到边缘特征点。(First deal with gray-scale pictures, and then carry out Gaussian filter, and finally get the edge feature point.)

基于区域方差的加权融合方法，主要解决原始图像分解的低频成分的结合(Weighted fusion method based on regional variance)

This is surf(Speeded Up Features Robust) matlab code for detection keypoint and construct descriptor and matching

利用模糊C聚类（FCM）的方法对彩色图像进行分割，期中可以用不通的特征向量来表征图像的特征(Using Fuzzy C-clustering (FCM) method for color image segmentation, mid-term feature vectors can be used unreasonable to characterize the image Feature)

采用模版匹配方法进行文字、局部图像的匹配....采用ssda算法(The template matching method for text, local image matching... The ssda algorithm)

快速非局部均值，用来消除噪声，效果良好，适合于细节较多的图像(Fast nonlocal means is used to eliminate noise and achieve good results, which is suitable for more detailed images.)

说明：  通过matlab实现理想低通滤波对图像处理，进行降噪(matlab,ILPF,noise reduction)

说明：  二维emd的MATLAB代码，需要下载rbf工具箱，亲测可用(Two-dimensional EMD MATLAB code, need to download the RBF toolbox, pro-test available)

matlab图像处理算法，包括中值滤波，平滑滤波，直方图滤波等(matlab image processing algorithms, including the median filter, smoothing filter, Histogram filtering)
