本人在写论文时自己编写的虹膜瞳孔的分割，采用二值化方法，并附有图片。希望有人和我一起研究。(I am writing papers prepared by his pupil iris division of the value of using two methods, accompanied by a caption. And I want people to see.)

Matlab图像处理教程简易教程 - /1、图像的读取和显示 /2、图像的点运算 /3、图像的几何变换 /4、空间域图像增强 /5、频率域图像增强 /6、彩色图像(Matlab image processing tutorial Easy Tutorial-/1, read and display image/2 image point operations/3, the image of geometric transformation/4 spatial domain image enhancement/5, the frequency domain image enhancement/6 color image)

对两幅图像进行相似度计算，基于相似度计算进行模板匹配，带有测试图像，可以直接运行(Calculate the similarity of the two images, the similarity calculation based on template matching, with a test image, you can directly run)

分别利用均值滤波、自适应滤波和中值滤波对噪声图像g1和g2进行滤波，利用峰值信噪比对去噪性能进行比较。(Respectively, using the mean filter, adaptive filtering and median filtering images g1 and g2 noise filtering, denoising performance comparison using the peak signal-to-noise ratio.)

基于模板匹配的人眼定位算法，代码简单易懂，定位精度高(The eye location algorithm based on template matching, the code simple, high positioning accuracy)

实现一个完整的OFDM系统，可以显示频谱图。(OFDM systems to achieve a complete, can be displayed spectrum.)

说明：  彩色图像分割，灰常不错。This function implements kmeans clustering on an input RGB (m x n x 3) image. The user inputs at least two inputs: IMGIN and NCLUSTERS, and this function will step through an interactive color segmentation using kmeans clustering. It is interactive in that the user will be prompted to click-define the target colors in the segmentation.(This function implements kmeans clustering on an input RGB (m x n x 3) image.
