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

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.
