在图形处理过程中出现上面的错误，如果你也有相同问题那么可以用以下方法来解决。
报错原因:cv2只能处理BGR格式图片,而image.open()读取的图片是RBG格式。
解决方式：把RBG图片转化成BGR格式，转化代码如下所示：
#将RGB转换成BGR方法
r,g,b = cv2.split(median)
out = cv2.merge([b,g,r])把上述代码插入到你的图片处理完毕的后面对准备输出图片进行转换就可以了。

imgproc: replace assertion in cornerSubPix with descriptive error #28404
Replace CV_Assert with explicit bounds check for initial corners in cornerSubPix.
This provides a descriptive runtime error instead of abrupt termination,
improving error handling for Python and C++ users.
No algorithmic or behavioral change for valid inputs.
Fixes #25139 (Related to #7276).
