Method Detail

fitModel

public boolean fitModel(java.util.List<AssociatedPair> dataSet,
                        Homography2D_F64 initial,
                        Homography2D_F64 found)

Description copied from interface: ModelFitter

Fits a model to a set of points. Note that initial and found can be the same instance.

Specified by:

fitModel in interface ModelFitter<Homography2D_F64,AssociatedPair>

Parameters:

dataSet - Set of points the model is being fit to.

initial - Initial hypothesis

found - The found model. Can be the same instance as initial.

Returns:

true if a model was found and false if one was not.

generate

public boolean generate(java.util.List<AssociatedPair> dataSet,
                        Homography2D_F64 model)

Description copied from interface: ModelGenerator

Creates a list of hypotheses from the set of sample points.

Specified by:

generate in interface ModelGenerator<Homography2D_F64,AssociatedPair>

Parameters:

dataSet - Set of sample points. Typically the minimum number possible.

model - Storage for generated model.

Returns:

true if a model was generated, otherwise false is none were

getMinimumPoints

public int getMinimumPoints()

Description copied from interface: ModelGenerator

The minimum number of points required to fit a data set

Specified by:

getMinimumPoints in interface ModelGenerator<Homography2D_F64,AssociatedPair>

Returns:

Number of points.
