python - Interpreting the output of image in open cv?

Question

I just started open cv and I'm trying to understand the output that I'm getting from imread function. This is the code:

img = cv2.imread('...')

The image width x height is 3744 X 2104

But in the img variable I have defined, I have a multi dimensional array with shape (2104, 3744, 3).

I would like to know what does this shape mean in terms of images.

When I iterate over img, each item has a shape (3744, 3) and there 2104 such values. What I want to know is why do we have 3 x 3744 values 2104 times. I expected a matrix of width x height I mentioned.

Answer 1

图像大小为 2104 x 3744 像素，“3”大概是颜色通道的数量，即红绿蓝
