cv2
uses numpy
for manipulating images, so the proper and best way to get the size of an image is using numpy.shape
. Assuming you are working with BGR images, here is an example:
>>> import numpy as np >>> import cv2 >>> img = cv2.imread('foo.jpg') >>> height, width, channels = img.shape >>> print height, width, channels 600 800 3
In case you were working with binary images, img
will have two dimensions, and therefore you must change the code to: height, width = img.shape
