图像识别，包括人脸识别和虹膜识别，在数字图像中虹膜位置的有效定位是虹膜识别的关键问题。用一种基于主动轮廓线模型的方法定位虹膜的位置，先用灰度投影法检测出瞳孔内的一点作为瞳孔的伪圆心，该圆心只要能落在瞳孔内部即可。(Image recognition, including face recognition and iris recognition, iris position in the digital image of the iris recognition and effective positioning is the key issue. Using a model based on active contour method of positioning the iris position, the first gray projection method used to detect a point within the pupil as a pupil of the pseudo-center of a circle, the center of a circle can be as long as it falls within the pupil.)

matlab函数，将多维矩阵的极值找出并定位，图像处理经常用到，很简单很好用(matlab function, multi-dimensional matrix to identify and locate the extreme, often used in image processing, it is very simple to use)

滤波器图像增强的matlab算法实现程序。本人自己给出的程序代码(gabor wavelet matlab algorithm. Program code given by the original author)

对离散特征点进行直线拟合，效果很好，文件中还有平面拟合的例子，以及三焦点张量的部分主要程序，希望对需要的人有帮助(Discrete feature point fitting a straight line, with good results, part of the main program file plane fitting example trifocal tensor hope that those who need help)

基于信息熵对图像进行加密，加密后的直方图已经抗攻击能力(Based on the information entropy of image encryption, the encrypted histogram has ability against the attack)

这里包含了多种图像倾斜角度矫正的方法 其中有huogh变换 radon变换 还有常规的线性检测角度 然后矫正它(This contains a variety of image angle correction method which huogh transform the linear radon transform routine testing point of view there and then correct it)

说明：  求矩阵的特征值和特征向量，使用c语言编程(Matrix eigenvalues and eigenvectors, c language programming)

说明：  matlab下使用帧差法实现视频跟踪，提供了一个测试视频和完整的说明文档 已验 无错 放心使用 改一下视频路径即可(matlab to use the frame difference method for video tracking, provides a test video and full documentation is error-free ease of use experience to change the path to your video)

说明：  图像处理算法质量评估，图像结构相似度（ssim)评价的matlab实现，并附带原始论文pdf(This is an implementation of the algorithm for calculating the Structural SIMilarity (SSIM) index between two images. Please refer to the following paper: Z. Wang, A. C. Bovik, H. R. Sheikh, and E. P. Simoncelli, "Image quality assessment: From error measurement to structural similarity" IEEE Transactios on Image Processing, vol. 13, no. 1, Jan. 2004.)

说明：  <基于Matlab的数字图像相关法的程序实现> 数字图像相关法是对全场位移和应变进行分析的一种新的实验力学方法。图像处理是其核心之一。本文探讨了根据相关技术寻 求位移场的基本原理,并编制了基于Matlab的数字图像相关法程序。程序验证结果表明本程序处理速度快,精度高,可以满足基于相关技 术的图像处理的要求。(err)
