R分量直方图阈值分割-R component histogram thresholding

阈值分割、边缘检测、线性变换、均衡直方图等图像预处理的一些代码-Some code for image preprocessing, such as threshold segmentation, edge detection, linear transformation and equalization histogram

区域生长的图像分割程序，将生长起始点灰度值存入seed中，记录每次判断一点周围八点符合条件的阈值-Area growth of the image segmentation program, the growth of the starting point gray value stored in the seed, the record every time around the point of eight points meet the threshold
