如何让OpenCv在两个颜色通道的组合中显示图像？

import cv2

# 读取图像
image = cv2.imread('image.jpg')

# 分离颜色通道
channels = cv2.split(image)

# 显示分离后的颜色通道图像
for i, channel in enumerate(channels):
    cv2.imshow('Channel {}'.format(i), channel)

cv2.waitKey(0)
cv2.destroyAllWindows()

import cv2

# 读取图像
image = cv2.imread('image.jpg')

# 分离颜色通道
channels = cv2.split(image)

# 选择两个颜色通道进行组合
combined_image = cv2.merge([channels[0], channels[1], channels[0]])

# 显示组合后的图像
cv2.imshow('Combined Image', combined_image)

cv2.waitKey(0)
cv2.destroyAllWindows()
