利用最小二乘法，可以自动实现图像中的椭圆检测并拟合出来，效果很好(Ellipse detection and fitting them to achieve)

非精确ALM解决PCA算法的例子，用后效果不错，发上来分享。(This matlab code implements the inexact augmented Lagrange multiplier method for Robust PCA.)

说明：  求lena图像的信息熵，图像大小为256X256(For lena image information entropy, image size is 256x256)

这个matlab程序是基于纹理的图像检索源码，纹理特征是图像的基本特征特征之一，所以基于纹理的图像检索是图像处理的热点。(The matlab program is based on the source texture image retrieval, texture image is characterized by one of the characteristics of the basic features, so texture-based image retrieval is a hot image processing.)

说明：  对图像进行纹理特征提取，有LBP，旋转不变lbp，统一lbp，小波特征提取等比较齐全的特征提取算法(Texture feature extraction of images, such as LBP, rotation invariant lbp, unified lbp, wavelet feature extraction and other relatively complete feature extraction algorithms)

对RGB图象的处理,一般要进行增强以达到去噪,锐化的功能,本程序在拉普拉斯算子基础上实现的(RGB images of the treatment, the general should be enhanced in order to achieve de-noising, sharpening function, the procedures in the Laplacian, based on the)

说明：  基于分水岭变换的浮选泡沫图像分割基于分水岭变换的浮选泡沫图像分割(GOODGOODGOODGOODGOODGOODGOODGOOD)

将一幅图像划分成8*8图像块，计算灰度梯度共生矩阵，基于混合熵对每个图像块分类(divide an image into 8*8 image blocks,calculate gray-gradient-matrix, classify image blocks based on the mixed entropy)

涉及功能点:移动选区 调整大小 放大镜 通知观察者 热键

这是一个利用matlab开发的程序，功能是用susan算法提取图像角点的。一个压缩包，程序可用哟。(This is a program developed using matlab, the functional algorithm is susan corner of image. A compact package, the procedure can be used yo.)
