python输出图像通道数_python查看图片通道数

src = cv.imread(“xxxxx”) 读取图片

image = src.shape 获取图片宽高及通道数
rows = image[0]
cols = image[1]

tongdao_nums = image[3]

def shape_size():
    img = cv2.imread('img_part.jpg')
    print(img.shape)  # h, w, c
    img1 = Image.open('img_part.jpg')
    print(img1.size)  # w, h
    img2 = io.imread('img_part.jpg')
    print(img2.shape)  # h, w, c
