如何使用python中的openCV在图像中进行均匀照明或如何增强非均匀照明图像中的照明

import cv2
import numpy as np

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

gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

kernel = np.ones((15, 15), np.float32) / 225
smoothed = cv2.filter2D(gray, -1, kernel)

diff = cv2.subtract(gray, smoothed)

enhanced = cv2.add(diff, 100)

output = cv2.add(enhanced, image)

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