Class TimeDelayChi2Delta

java.lang.Object

clickTrainDetector.clickTrainAlgorithms.mht.mhtvar.SimpleChi2Var

clickTrainDetector.clickTrainAlgorithms.mht.mhtvar.TimeDelayChi2Delta

All Implemented Interfaces:

MHTChi2Var<PamDataUnit>, Cloneable

public class TimeDelayChi2Delta
extends SimpleChi2Var

Chi^2 value for time delays. This might be a little more robust than bearing, especially for hydrophone arrays with more than two hydrophones.

public TimeDelayChi2Delta()

Method Details

getName

public String getName()

Description copied from interface: MHTChi2Var

Get the name of the chi^2 variable.

Returns:

the name of the chi^2 variable.

getUnits

public String getUnits()

Description copied from interface: MHTChi2Var

Get the data units for the MHTChi2 var.

Returns:

the units.

updateChi2

public double updateChi2(PamDataUnit newdataUnit,
 BitSet bitSet,
 int bitcount,
 int kcount,
 IDIManager idiManager)

Description copied from interface: MHTChi2Var

Update the existing chi2 value with a new data unit and track bitset.

Specified by:

updateChi2 in interface MHTChi2Var<PamDataUnit>

Overrides:

updateChi2 in class SimpleChi2Var

Parameters:

newdataUnit - - the new data unit.

bitSet - - the bitset for the track.

bitcount - - the number of detections in the track.

kcount - - the current kcount, the total number of detections added to possibility mix.

idiManager - - the IDI manager.

Returns:

the new chi^2 value

getDiffValue2

protected double[] getDiffValue2(PamDataUnit lastDataUnit,
 PamDataUnit newdataUnit)

Parameters:

lastDataUnit -

newdataUnit -

Returns:

calcDeltaChi2

public double calcDeltaChi2(double[] lastDelta,
 double[] newDelta,
 double timeDiff)

Calculate the chi2 for two different delta values.

Parameters:

lastDelta - - the first delta value

newDelta - - the second delta value

timeDiff - - the time difference for error calculation

Returns:

the chi^2 value.

getDiffValue

public double getDiffValue(PamDataUnit pamDataUnit0,
 PamDataUnit pamDataUnit1)

Description copied from class: SimpleChi2Var

Get the difference in value between two sequential data units. This is top of the chi2 equation.

Description copied from class: SimpleChi2Var

Get the error value between two sequential data units. This is denominator of the chi2 equation.

Specified by:

getErrValue in class SimpleChi2Var

Parameters:

pamDataUnit0 - - the first data unit.

pamDataUnit1 - - the second data unit.

Returns:
