OpenCV - Intersection between two binary images

Question

Let\'s say I have two binary images of the same size. How do I find the intersection between the two binary images? Only pixels of the same coordinate (location) on the two imag

Answer 1

Here's how to do this in python (with the images above):

import cv2

img1 = cv2.imread('black_top_right_triangle.png',0)
img2 = cv2.imread('black_bottom_right_triangle.png',0)

img_bwa = cv2.bitwise_and(img1,img2)
img_bwo = cv2.bitwise_or(img1,img2)
img_bwx = cv2.bitwise_xor(img1,img2)

cv2.imshow("Bitwise AND of Image 1 and 2", img_bwa)
cv2.imshow("Bitwise OR of Image 1 and 2", img_bwo)
cv2.imshow("Bitwise XOR of Image 1 and 2", img_bwx)
cv2.waitKey(0)
cv2.destroyAllWindows()

If you need to install OpenCV for Python, save time by following these directions (installation has historically been quite a pain).
