Arithmetic Operations on Images - OpenCV

Bitwise Operations. This includes the bitwise AND, OR, NOT, and XOR operations. They will be highly useful while extracting any part of the image (as we will see in coming chapters), defining and working with non-rectangular ROI's, and etc. Below we will see an example of how to change a particular region of an image.

Bitwise XOR of All Pairings - docs.vultr.com

The problem involves computing the Bitwise XOR for all pairings between two sets of integers. In Python, given two lists set1 and set2, calculate this combined XOR based on certain conditions. Initialize two integers xor_result1 and xor_result2 to zero, which will store the interim XOR results of elements from set1 and set2 respectively.
