      ch.unizh.ini.jaer.projects.opticalflow.graphics.OpticalFlowDisplayMethod

public class OpticalFlowDisplayMethod
extends DisplayMethod

Displays output from an OpticalFlowChip. Optionally displays the photoreceptor and the local motion vectors. The local motion vectors are displayed either as color (red/blue) or as motion vector arrows. The global motion vector that is displayed is computed from the vector sum of local motion vectors. (The "global motion" vector captured from the chip is actually just a corner pixel.)
