使用CS算法仿真理想点目标的成像，并且使用CLEAN算法来提取理想点目标(use chirp scaling algorithm to simulate the ideal point target s imaging,and use CLEAN algorithm to calculate the ideal point target)

实现论文 Active Contours without Edges 中提出的CV活动轮廓模型，用于分割图像。(To achieve paper Active Contours without Edges, in the CV active contour model for image segmentation.)

KSVD算法的工具包，安装在matlab的相关路径下，可以直接调用。(KSVD algorithm Kit installed in the path of matlab can be called directly.)

本代码可以实现统计彩色图像RGB三个通道内的交流分量，通过对比确定，图像是否经过高斯模糊篡改。(This code can realize statistical color image RGB three channels in the ac component, by comparing the sure, whether image through gaussian blur manipulation.)

说明：  使用pca方法对图像进行特征提取，对训练集的20个人的共一百张人脸进行训练，使用adaboost算法生成强分类器，可以对测试集的人脸图片进行识别，且识别率较高(The PCA method is used to extract the features of the image, and the training is carried out for a total of 100 faces of 20 people in the training set. The AdaBoost algorithm is used to generate a strong classifier, which can recognize the face images in the test set with a high recognition rate)

这里不但有标准的局部二值模式的代码，还有局部二值模式的一些扩展代码！(err)

一种基于特征点的图像匹配算法 一种基于特征点的图像匹配算法(Feature point based image matching algorithm based on feature points matching algorithm)

简单的huffman编解码例子，对于初学者会有很大的帮助。(Simple huffman codec examples, for beginners, there will be a great help.)

利用低通滤波器对图像进行插值放大：按放大的倍数对原图像进行插零，插零后的图片与低通滤波函数进行卷积，原先插入的零的位置自动替换为适当的插值，如此图像就已经插值放大了，图像质量还不错。(Double the number of pixels of each row and column by adding a zero value pixel between each pixel of the image.Then operate with two kinds of low-pass filters to get the enlarged image.)

基于NCC（归一化互相关）的图像配准算法(NCC (normalized cross-correlation), image registration algorithm)
