峰值信噪比

自己实现的sift特征提取的matlab代码，可以计算特征描述子用于图像匹配，不过速度有点慢(Own implementation of sift feature extraction matlab code to calculate feature descriptors for image matching, but a bit slow)

贝叶斯小波去噪是基于小波变换得软阈值贝叶斯去噪算法。(Bayesian wavelet denoising is wavelet-based Bayesian denoising was soft-thresholding algorithm.)

用matlab进行图像检索，基于边缘直方图（EHD）描述子，它是MPEG-7标准中提出的一种边缘描述子，它具有描述图像亮度变化的方向和频率的能力。资料为主程序代码。(Matlab for image retrieval, based on the description of the edge histogram (EHD) sub, it is proposed in the MPEG-7 standard descriptor an edge, it has the direction of the change and the frequency of the described image brightness capability. Data the main program code.)

识别结果详见下图，识别图像不错的例子

国外的牛人写的软件，数据降维工具箱，包含了几十种常用的流形学习方法的源码，自带图形界面。(A foreign master write this dimension reduction toolbox,there s dozens of code of common manifold learning methods. )

通过matlab编写的几个关于psnr、mse的图像处理的小程序(Through several matlab written on the PSNR, MSE image processing of small procedures psnr_nmse_rms)

Multiclass Spectral Clustering Algorithm，和Dominant-set算法同属于较常用的聚类算法，用于图像分割等(Multiclass Spectral Clustering Algorith m, and Dominant-set algorithm is more commonly used with the clustering algorithm for image segmentation, etc.)

通过边缘检测寻找图像上圆点的圆心坐标，可用于大量的图像处理程序(Image through edge detection to find the center coordinates of the dots)

将RGB格式的图片进行mosaic处理得到RawData格式的图片，然后再恢复成RGB格式彩色图片,laroche-CFA插值算法(turn an RGB picture to RawData picture，then recover the RawData picture to an RGB picture.it is called laroche-CFA.)

本代码是用Matlab实现图像的超分辨率重建，方法为凸集投影法，能从多幅低分辨率图像重建一幅高分辨率图像。(We use Matlab to reconstruct image. The method is convex projection on suoer-resolution(POCS).)
