您可以在Python/OpenCV中进行除法规范化。

• 读取输入
• 转换为灰度
• 应用高斯模糊
• 将灰度图像除以模糊图像
• 保存输出

输入：

import cv2
import numpy as np

# read the image
img = cv2.imread('equation.png')

# convert to gray
gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

# blur
smooth = cv2.GaussianBlur(gray, None, sigmaX=100, sigmaY=100)

# divide gray by morphology image
division = cv2.divide(gray, smooth, scale=255)

# save results
cv2.imwrite('equation_division.jpg',division)

# show results
cv2.imshow('smooth', smooth)  
cv2.imshow('division', division)  
cv2.waitKey(0)
cv2.destroyAllWindows()

结果：
