@DSBxASSASSIN i change the this code: contours, hierarchy = cv2.findContours(img.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_NONE)
I write this code: (_, contours, hierarchy) = cv2.findContours(img.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)
end I am using computer camera for this reason this code cap = cv2.VideoCapture(0) it has to practec in zero
