Description

Hi everyone.

I was checking the official docs of the java bindings in OpenCV and saw that there were some objects with overloaded operators. For instance, & or | in Rect types for intersection or union operations. I tried such thing in JavaCV but it seems such operations haven't been implemented as an operator overload. Is there a way to perform an intersection between 2 Rect objects?

Best regards.

Contributor guide

Research direction
Investigate the existing Rect class in JavaCV to see if methods like intersect() and union() already exist. If not, study the C++ OpenCV Rect operator overloads (e.g., operator& for intersection, operator| for union) and implement equivalent Java methods. Then add tests and documentation.
