template - template

Method Detail

updateAppearance

public void updateAppearance()

Update the appearance model parameters

convertParams

public float[] convertParams(double[] params)

Convert parameters for better behaviour in an optimsation routine

Parameters:

params - the parameters

Returns:

return the converted parameters

reconvertParams

public double[] reconvertParams(float[] fparams)

Reconvert the parameters

Parameters:

fparams - the parameters to reconvert

Returns:

returns the reconverted parameters

func

public double func(double[] params)

Description copied from class: Powell

Func should be overrided to calculate the error given the parameters params

Specified by:

func in class Powell

Parameters:

params - the parameters to evaluate

Returns:

returns the error

onIteration

public void onIteration(double[] params)

Description copied from class: Powell

onIteration is called once per complete itrations to show the best current guess. It can be implemented with an empty body if not needed

Specified by:

onIteration in class Powell

Parameters:

params - the current params of the model

solveSingle

public Template solveSingle(int maxits,
                            double converged)

A single iteration of the detection process

Parameters:

maxits - the maximum iterations to use

converged - converged when change in error is less than this, or maxits exceeded

Returns:

returnt the estimated Template

solve

public Template solve(int maxAppIts,
                      int maxits,
                      double converged)

Estimate the template iteratively

Parameters:

maxAppIts - the maximum appearance iterations

maxits - the maximum shape iterations

converged - converged when change in error is less than converged, or maxAPpIts exceeded

Returns:

returns the estimated Template

main

public static void main(java.lang.String[] args)
