We can retrieve and use many image properties with OpenCV functions. Take a look at the following code:
import cv2 img = cv2.imread('lena_color_512.tif',1) print img.shape print img.size print img.dtype
img.shape operation returns the shape of the image, that is, its dimensions and the number of color channels. The output of the previously listed code will be as follows:
(512, 512, 3) 786432 uint8
If the image is colored, then
img.shape returns a triplet containing the number of rows, the number of columns, and the number of channels in the image. Usually, the number of channels is three, representing the red, green, and blue channels. If the image is grayscale, then
img.shape only returns the number of rows and the ...
