filterPacket

public EventPacket<?> filterPacket(EventPacket<?> in)

This filterPacket method assumes the events have PolarityEvent type

Specified by:

filterPacket in class EventFilter2D

Parameters:

in - the input packet

Returns:

the output packet, where events have possibly been deleted from the input
