Method Detail

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

getFilterState

public java.lang.Object getFilterState()

Description copied from class: EventFilter

should return the filter state in some useful form

Specified by:

getFilterState in class EventFilter

resetFilter

public void resetFilter()

Description copied from class: EventFilter

should reset the filter to initial state

Specified by:

resetFilter in class EventFilter

initFilter

public void initFilter()

Description copied from class: EventFilter

this should allocate and initialize memory: it may be called when the chip e.g. size parameters are changed after creation of the filter

Specified by:

initFilter in class EventFilter
