CV_BGR2HSV 在转换图像的时候是将 H / 2 ---> H ,我们知道图像中色相H的取值范围为 0-360 ,所以利用opencv转换之后得到的H的范围为 0-180 而CV_BGR2HSV_FULL 实现的映射是 H * 255 / 360 --->H , 所以利用_FULL 这个转换得到的H通道图像的范围为 0-255 这两种方式都是opencv把[0-360] 的数...

OpenCV颜⾊空间转换参数CV_BGR2GRAY改变 OpenCV的颜⾊空间转换函数：C++: void cvtColor(InputArray src, OutputArray dst, int code, int dstCn=0 )参数dstCn原来⼀直沿⽤CV_BGR2GRAY, CV_RGB2GRAY, CV_GRAY2BGR, CV_GRAY2RGB等格式，但最新⼏个版本的OpenCV已改为COLOR_BGR2GRAY类似形式，今天才看...
