Extractionoffaultfeaturevector

用于计算均匀圆球的mie散射，matlab 程序，可计算散射系数，消光截面等(It is used to calculate the Mie scattering of uniform spheres. The matlab program can calculate the scattering coefficient and extinction section.)

自己编写的粒子滤波程序，请用户自己添加视频测试(Their own procedures for the preparation of the particle filter, please add the user' s own Video Test)

整理了五种多曝光图像融合的代码，用于图像处理，图像去雾，有英文介绍(Five kinds of multi-exposure image fusion codes are sorted out.For image processing, image defogging, with English introduction)

在梯度基础上使用加权平均提取指纹方向场然后使用高斯滤波进行平滑处理(Extraction of fingerprint orientation field using weighted average based on gradient)

说明：  实现图片、文本隐藏在图片中，并导出等操作(Implement images, text hidden in images, and export operations)

RANSAC算法实现数据拟合，用此算法可以实现多视角图像匹配等(RANSAC algorithm for data fitting, using this algorithm can realize multi-angle image matching, etc.)

说明：  根据：一种可识别破碎图形的特殊广义Hough变换方法 论文，在matlab上做的实验源码，有模版生成，广义哈夫变换代码(In accordance with: A broken identifiable graphics special generalized Hough transform methods papers, in matlab to do experiments on the source, there are template generation, generalized Hough transform code)

按照最邻近原则把待分类样本点分到各个簇。然后按平均法重新计算各个簇的质心，从而确定新的簇心。一直迭代，直到簇心的移动距离小于某个给定的值。(According to the nearest neighbor principle, the sample points to be classified are divided into clusters. Then the centroid of each cluster is recalculated according to the average method to determine the new cluster center. Iterate until the moving distance of the cluster center is less than a given value)

矫正桶形畸变，只是用了坐标变化，目前在研究张正友的算法，日后会上传的(correct the distortion of picture)

说明：  m-map工具箱，可以帮助画图，比如世界地图的背景(M-map toolbox, can help draw pictures, such as the background of the world map)
