图片通道转换

def change_image_channels(image):
    # 3通道转单通道
    if image.mode == 'RGB':
        r, g, b = image.split()#分离通道函数
    return b
import numpy as np
from tqdm import tqdm
import os
import cv2
path=#图片路径
save_path=#图片保存路径
image = Image.open(path)
image1=change_image_channels(image)
image1=np.array(image1)
cv2.imwrite(save_path,image1)
