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 images that are white (gray – 255) will give white pixels on the output image (intersection).

    You can use cvAnd or cv::bitwise_and on the two images. The resulting image will be white only where both the input images are white.

    EDIT: Here are the results of applying cv::bitwise_and, cv::bitwise_or and cv::bitwise_xor on binary images:

    These are the two source images:

    image 1 image 2

    Here is the result of applying cv::bitwise_and:

    imgAnd

    Here is the result of applying cv::bitwise_or:

    imgOr

    Here is the result of applying cv::bitwise_xor:

    imgXor
