Read Multiple images on a folder in OpenCv (python)

Question

I want to read multiple images on a same folder using opencv (python). To do that do I need to use for loop or while loop with imread func

Answer 1

This one has better time efficiency.

def read_img(img_list, img):
    n = cv2.imread(img, 0)
    img_list.append(n)
    return img_list

path = glob.glob("*.bmp") #or jpg
list_ = []`

cv_image = [read_img(list_, img) for img in path]
