从文件夹中读取所有图像并将其转换为单个通道图像并保存

Question

我想保存RGB图像中的单通道图像，当我拍摄一张图像时可以使用，但是当我拍摄多张图像时出现问题

from glob import glob
import os 
import numpy as np
def load_data(path):
    img_list = []
    for img in glob(os.path.join(path,"*.jpeg")):
        image = cv2.imread(img)
        img_list.append(image)  
    return img_list    
p = load_data(path)
path = 'F:/EyePac/eye/class/Train_1'
img_array = np.array(p)
rgb = img_array[1]
r = rgb_r.copy()
r[:,:,1]=0
r[:,:,2]=0
