Class EpipolarRectification

java.lang.Object
  net.sf.jaer.eventprocessing.EventFilter

          net.sf.jaer.eventprocessing.filter.EpipolarRectification

All Implemented Interfaces:

java.util.Observer

public class EpipolarRectification
extends EventFilter2D
implements java.util.Observer

This filter apply the epipolar correction (loading pixel correspondance tables previously computed using matlab or other tools) to one retina only here (epipolar correction is appply to two retinas used in stereo but slightly angled toward each other) so that pixel at the same height appears on the same y line) One must select which retina to correct, left or non left (should be easily adapted to any configuration) To correct both retinae, one must use two instances of this filter

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.
