Python 20.opencv 直方图均衡化，CLAHE（对比度改变）

import cv2
import numpy as np

img = cv2.imread('pic1.png', 0)
# 进行直方图均衡化
equ = cv2.equalizeHist(img)
# CLAHE有限对比适应性直方图均衡化
clahe = cv2.createCLAHE(clipLimit=2.0, tileGridSize=(8, 8))
cl1 = clahe.apply(img)

# 将三幅图像拼接在一起
res = np.hstack((img, equ, cl1))

cv2.imshow('img', res)
cv2.waitKey(0)
cv2.destroyAllWindows()
