org.openimaj.math.geometry.transforms.residuals.SymmetricTransferResidual2d<M>

Type Parameters:

M -

All Implemented Interfaces:

ResidualCalculator<Point2d,Point2d,M>

public class SymmetricTransferResidual2d<M extends Model<Point2d,Point2d> & MatrixTransformProvider>
extends Object
implements ResidualCalculator<Point2d,Point2d,M>

The points in the first image are projected by the homography matrix to produce new estimates of the second image points and the second image point projected by the inverse homography to produce estimates of the first. Residuals are computed from both point sets and summed to produce the final geometric residual value.

public SymmetricTransferResidual2d()

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> & MatrixTransformProvider>

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> & MatrixTransformProvider>

Parameters:

data - the data

Returns:

the error

computeResiduals

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

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> & MatrixTransformProvider>

Parameters:

data - the data

residuals - the array to write the residuals into
