Facial recognition and arrays

Hi ,
I looked at other reverse array topics but nothing seems to work with my sketch.
I'm working with code that draws a tree and I've used OpenCV to draw only when it sees your face. I would like to reverse the array when it stops seeing it, instead of just pausing the drawing. Would anyone know how to do this?
Thanks!
