如何在Python OpenCV中删除图像的某些部分？

import cv2
import numpy as np

image = cv2.imread('image.jpg')

mask = np.zeros(image.shape[:2], dtype=np.uint8)

points = np.array([[100, 100], [200, 100], [200, 200], [100, 200]])
cv2.drawContours(mask, [points], -1, (255), thickness=cv2.FILLED)

result = cv2.bitwise_and(image, image, mask=mask)

cv2.imshow('Result', result)
cv2.waitKey(0)
cv2.destroyAllWindows()
