推荐答案

如果您的所有图像都是这样，并且如问题中所示的带有水印的水印带有浅灰色水印，则可以使用简单的阈值操作.

If all your images are like this and have a watermark as shown in the question having a light gray watermark then a simple thresholding operation will work.

import cv2

img = cv2.imread('watermark.jpg')
_, thresh = cv2.threshold(img, 150, 255, cv2.THRESH_BINARY)
cv2.imshow('Result', thresh)
cv2.waitKey(0)
cv2.destroyAllWindows()
