@nitroey , if you are still looking OpenCVForUnity related ~ You can crop the ROI after face detection. Just use the Mat(Mat m , Rect ROI ) constructor.

The rectangle is drawned on the texture. The best way I can think of would be to create a transparent button on screen and move it around. The exercise is to convert the texture coordinates to screenPoint coordinates you can do it :D
