Class DataConverter<S,T>

java.lang.Object

de.unihalle.informatik.Alida.operator.ALDOperator

de.unihalle.informatik.MiToBo.core.operator.MTBOperator

de.unihalle.informatik.MiToBo.tracking.multitarget.datatools.DataConverter<S,T>

Type Parameters:

S - input data type

T - output data type

All Implemented Interfaces:

de.unihalle.informatik.Alida.datatypes.ALDConfigurationValidator, de.unihalle.informatik.Alida.operator.events.ALDOperatorExecutionProgressEventListener, EventListener

public abstract class DataConverter<S,T>
extends MTBOperator

An operator class to convert between data types. The class provides static methods for simple use. The implementations of the abstract DataConverter class are located within the static methods to reduce the number of operator class files (have a look at the implemented conversion methods)

Convert observations to regions.

Throws:

observationsToTracks

public static HashMap<Short,int[]> observationsToTracks(Vector<MultiState<MotionModelID>> observations,
                                                        HashMap<Integer,Vector<Integer>> clutterObs)

Obtain observations assigned to each target from observations with assigned target IDs

Parameters:

observations - observations with target IDs assigned (ID=0 means clutter)

clutterObs - if this map is not null, all clutter observations per time step are stored here (the map is cleared before)

Returns:

a map that for each target ID holds an array which stores for each time step the observation associated the target, or -1 if no observation was associated or -2 if targets was not yet observed or after last observation
