Constructor Detail

HmmFilter

public HmmFilter(AEChip chip)

Creates a new instance of HmmFilter

Method Detail

filterPacket

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

Description copied from class: EventFilter2D

Subclasses implement this method to define custom processing.

Specified by:

filterPacket in class EventFilter2D

Parameters:

in - the input packet

Returns:

the output packet

getFilterState
