Class EyeFilter

java.lang.Object
  net.sf.jaer.eventprocessing.EventFilter
      net.sf.jaer.eventprocessing.EventFilter2D
          net.sf.jaer.stereopsis.EyeFilter

All Implemented Interfaces:

java.util.Observer

public class EyeFilter
extends EventFilter2D
implements java.util.Observer

This filter processes BinocularEvents (generated by the stereoboard chip for example) to let pass event through according to two criteria : Left or Right retina and (added for convenience) ON or OFF events (This filter may be slowing down real-time applications)

Method Detail

getDescription

public static java.lang.String getDescription()

filterPacket

public EventPacket filterPacket(EventPacket in)

filters in to out. if filtering is enabled, the number of out may be less than the number put in

Specified by:

filterPacket in class EventFilter2D

Parameters:

in - input events can be null or empty.

Returns:

the processed events, may be fewer in number. filtering may occur in place in the in packet.
