更改蒙版的颜色OpenCV 3

import cv2
import numpy as np

# 加载图像
image = cv2.imread('image.jpg')

# 创建蒙版
mask = np.zeros(image.shape[:2], dtype=np.uint8)
mask[100:300, 200:400] = 255

# 更改颜色
masked_image = cv2.bitwise_and(image, image, mask=mask)

# 应用新颜色
new_color = (0, 255, 0)  # 新的颜色为绿色
colored_image = cv2.addWeighted(masked_image, 1, np.array(new_color), 0, 0)

# 显示结果
cv2.imshow('Original Image', image)
cv2.imshow('Masked Image', masked_image)
cv2.imshow('Colored Image', colored_image)
