OpenCV meanStdDev的解释 meanStdDev: 计算矩阵的均值和标准偏差。 C++: void meanStdDev(InputArray src,OutputArray mean, OutputArray stddev, InputArray mask=noArray()) Python: cv2.meanStdDev(src[,mean[, stddev[, mask]]]) → mean, stddev C: void cvAvgSdv(constCvArr* arr, CvScalar* mean, CvS...

返回minLoc和maxLoc的坐标位置是以OpenCV中(x,y)的形式组织的,但是在numpy中下标访问是按照array[行][列]形式,类似于array[y][x]的形式,所以minLoc和maxLoc的坐标值不能直接用于numpy的下标访问,需要对调后才可以使用,通过下面的例子可以得到验证,在前面的例子中极值的位置是(265, 198), (415, 8): #错误的...
