对usb视频图像进行实时采集，并进行处理(Usb video images in real-time acquisition and processing)

sift特征提取，包括三部分，特征点提取，特征点描述，特征点匹配(sift feature extraction consists of three parts, feature extraction, feature point description, feature point matching.)

说明：  一些简单的对图像的处理和直方图均衡化的复刻，可帮助初学者增加认知(Some simple image processing and histogram equalization can help beginners increase cognition)

该程序实现了相位编组法检测，可以将灰度缓慢变化的边缘提取出来(Realize the process of phase formation assay can be gray-scale changes in the edge of the slow extracted)

目前MATLAB里边对于多点计算仿射矩阵普遍采用RANSAC法，但是比较麻烦计算量也相对较大，通过最小二乘法来进行仿射矩阵的估计能够大大提高该效率，所以奉上自己在实验室写的仿射矩阵估计函数，来弥补matlab函数库在这方面的不足。(The MATLAB inside for calculating affine matrix commonly used RANSAC method, but more trouble calculation is relatively large, estimated by the least squares method to the affine matrix can greatly improve the efficiency, so give yourself in laboratory to write the estimated affine matrix function, to compensate for the lack of MATLAB Library in this area.)

用Python语言实现Poisson Image Editing（泊松图像编辑）算法(implementation of Poisson Image Editing algorithm with python.)
