自己写的两副图像的特征点匹配，其中用了opencv类库，功能包括：特征点的亚像素精度检测，特征点初始匹配，基本矩阵计算及对极约束引导匹配等。-himself wrote the two images and matching feature points, which used the OpenCV library, features include : the feature points subpixel accuracy testing, the initial matching feat

八邻域极大值检测，矩阵的极大值不变，其余置0-Eight neighborhood maxima detected, the maxima of the matrix is ​ ​ unchanged, and the rest is set to 0

基于hessian矩阵和各向异性扩散滤波相结合的血管检测-Based on the hessian matrix and the anisotropic diffusion filter combined detection of blood vessels
