convexitydefects opencv
首先介绍今天主角：void convexityDefects(InputArray contour, InputArray convexhull, OutputArray convexityDefects) 使用时注意，最后一个参数convexityDefects 是存储Vec4i 的向量(vector)，函数计算成功后向量的大小是轮廓凸缺陷的数量，向量每个元素Vec4i存储. , Convexity hull, Convexity defects. 如上图所示，黑色的轮廓线为convexity hull, 而convexity hull与手掌之间的部分为convexity defects. 每个convexity defect区域有四个特征量：起始点（startPoint），结束点(endPoint)，距离convexity hull最远点(farPoint)，最远点到convexity hull的距离(depth)。 二．OpenCV中的相关 ...
