OpenCV is a very popular and powerful image processing library written in C/C++. It has lots of code for OpenCV is typically used for image processing but it is a more general purpose library than that The green rectangle (r3) shown in figure below is the the union of red rectangles (r1 and r2). Those are two functions (intersection and union) that have already been provided by rectangle class in OpenCV
