Python opencv2 (cv2) wrapper get image size?
How to get size of image in
cv2 wrapper in Python OpenCV (numpy). Is there a correct way to do that than
numpy.shape(). How to get it in format dimensions: (width, height) list?
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
