使用python以圆形方式裁剪图像并粘贴到另一图像上

import cv2
import numpy as np

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

result = np.zeros_like(image)

height, width = image.shape[:2]
center_x = width // 2
center_y = height // 2
radius = min(center_x, center_y)

mask = np.zeros((height, width), dtype=np.uint8)

cv2.circle(mask, (center_x, center_y), radius, (255), -1)

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

result[center_y - radius:center_y + radius, center_x - radius:center_x + radius] = cropped_image

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