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()

Result

Let me know if this works for you

  • Thanks, it worked for me, but in doing this, some of the characters I want to keep are losing thickness. Is there any way to subtract just the watermark from the system without losing any other information? – Anmol Deep Apr 07 '23 at 10:40
