用于产生离散高斯函数的Matlab源代码。(Discrete Gaussian function used to produce the Matlab source code.)

说明：  首先对指纹图像进行预处理，包括图像的分割，增强，二值化，细化。对细化后的图像进行特征点的提取，最后通过细节特征匹配完成指纹的识别。(Firstly, the fingerprint image is preprocessed, including image segmentation, enhancement, binarization and thinning. The refined image is extracted by feature points, and the fingerprint recognition is completed by minutiae feature matching.)

使用OpenCV实现特征点的查找以及两幅图像中的特征点匹配(Use the function findHomography to find the transform between matched keypoints. Use the function perspectiveTransform to map the points)

说明：  利用相位一致性提取图像边缘，K-means聚类后区域生长进行图像分割，附参考论文。(Using phase coherence image edge extraction, K-means clustering image after region growing segmentation, attached reference paper.)

基于kalman滤波的图像目标识别的matlab代码，将运动目标从背景中分离出来(Kalman filter based on image recognition of matlab code, will be moving targets separated from the background)

Roberts算子，Prewitt算子，Sobel算子，Marr算子，Canny算子之一对输入图像 实现边缘检测，输出边缘图像并与matlab自带函数实现进行对比(Roberts operator, Prewitt operator, Sobel operator, Marr operator, Canny operator to achieve one of the input image edge detection, the output edge image and bring their own matlab function compared)

这是人脸识别，用MATLAB实现，非常好的东东哦(This is the face recognition, MATLAB, very good Eastern oh)

此程序用于画混沌系统的相图及其分叉图，使用时只需要写出相应的混沌微分方程，便可画出相应的图(This procedure for drawing the phase diagram of chaotic systems and its Poincare section, when used only need to write the corresponding chaotic differential equations, will be able to draw the corresponding graph.)

说明：  自己编写的图像腐蚀与膨胀matlab代码，经试验证明与matlab中自带的腐蚀和膨胀函数运行效果相同，可供初学图像处理的同学参考使用。(The image corrosion and expansion matlab code written by myself has been proved to be the same as the corrosion and expansion function of the matlab. It can be used by students who are ready for beginner image processing.)
