Pam-diff is a Node.js module that measures pixel differences between PAM image pixel arrays, supporting RGB, RGB alpha, and grayscale tupltypes. It's designed for video motion detection projects, allowing users to target all pixels, specific regions, or masked areas when comparing images. The module emits events or calls callbacks when differences are detected, providing detailed information about the changes including percentages and optional bounds or blob data.
