使用OpenCV（Python）的图像遮罩

我制作了这个代码，创建了两个面具。应用时，结果如下：

我知道代码，它一点也不好，但它能完成它的工作。如何改进它？

以下是一些建议：

import cv2
import numpy as np

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

h, w = frame.shape[:2]
mask_color = (0, 50, 255) # isolate a repeating constant

# avoid setting a variable that is used only once, only if you REALLY need it to improve readability
# that's why `upper_value` and `lower_value` were removed. 
# BTW, `lower_value` was unused in your code.

upper_mask = cv2.rectangle(frame, (0, 0), (w, int(0.5 * h)), mask_color, -1)
lower_mask = cv2.rectangle(frame, (0, h), (w, int(0.7 * h)), mask_color, -1)

你在寻求什么改进？一个更可读的代码？是的，可读并且可能有效。谢谢。你想要什么改进？一个更可读的代码？是的，可读并且可能有效。谢谢
