I want to resize an image with cv2 so that the image is only as big as 100x100 and display it with imshow.

Is there a function in cv2 that leaves out part of the image?

Thanks to busybyte I found the answer:

img = cv.imread("PATH")
centerx, centery = [int(img.shape[0] / 2) - 50, int(img.shape[1] / 2) - 50]
img = img[centerx:centerx + 100, centery:centery + 100]

Which crops the image to the wanted size of 100x100 from the centre.

A minor point: you are not "shrinking" the image, you are just "cropping" the image – Guang Aug 05 '21 at 17:23
I meant the same, but yes no shrinking just cropping! – Phil Aug 06 '21 at 07:31
