polygon

Detected polygon. If no polygon was detected - empty list. Points of polygon are normalized values between 0 and 1 relatively to the size of the frame.

For instance, point.x = 0.5f means that point is centered horizontally in the frame. point.y = 1.0f means that point is at the bottom of the frame and so on.

Note, that points are not rotated by .frameOrientation.
