Constructor Detail

TransformedSITR2d

public TransformedSITR2d(Jama.Matrix t1,
                         Jama.Matrix t2)

Construct with the given transforms

Parameters:

t1 - transform for first point in the pair

t2 - transform for second point in the pair

Method Detail

setModel

public void setModel(M model)

Description copied from interface: ResidualCalculator

Set the current model being evaluated. This should be called every time the model has changed internally, as the ResidualCalculator might pre-cache variables based on the model for error computation.

Specified by:

setModel in interface ResidualCalculator<Point2d,Point2d,M extends Model<Point2d,Point2d>>

Parameters:

model - the model

computeResidual

public double computeResidual(IndependentPair<Point2d,Point2d> data)

Description copied from interface: ResidualCalculator

Compute the residual for a single point

Specified by:

computeResidual in interface ResidualCalculator<Point2d,Point2d,M extends Model<Point2d,Point2d>>

Parameters:

data - the data

Returns:

the error

computeResiduals

public void computeResiduals(List<? extends IndependentPair<Point2d,Point2d>> data,
                             double[] errors)

Description copied from interface: ResidualCalculator

Compute the residual for a set of data points

Specified by:

computeResiduals in interface ResidualCalculator<Point2d,Point2d,M extends Model<Point2d,Point2d>>

Parameters:

data - the data

errors - the array to write the residuals into
