public class DrawStub
extends Stub
Sets up a special filter to reverse the image, and find the hand in the frame. The hand is the object furthest from the left part of the image. Since the camera sees the person's right hand on the left side of the frame. The frame is reversed so the person has an easier way of viewing themselves; like looking in a mirror.
