value越大，美颜效果越好

import  cv2
import time

if __name__ == '__main__':
    image = cv2.imread('d:/3.jpg')
    value = 15

    for i in range(10):
        start=time.time()

        image_dst = cv2.bilateralFilter(image, value, value * 2, value / 2)
        # dst = cv2.bilateralFilter(src=image, d=0, sigmaColor=100, sigmaSpace=5)
        print('time',time.time()-start)
    cv2.imwrite("d:/222.jpg",image_dst)
    # cv2.namedWindow('bi_demo', 0)
    # # cv2.resizeWindow('bi_demo',300,400)
    # cv2.imshow("bi_demo", image_dst)
    # cv2.waitKey(0)
