Method Detail

getName

public java.lang.String getName()

Description copied from class: Distorter

A name for this object

Specified by:

getName in interface Component

Specified by:

getName in class Distorter

getDescription

public java.lang.String getDescription()

Description copied from class: Distorter

What does this object do?

Specified by:

getDescription in interface Component

Specified by:

getDescription in class Distorter

isInverse

public boolean isInverse(Transformer test)

Description copied from class: Transformer

Are these two transformations, inverses of each other? This method is used to optimize a series of transformations where transformations.

Specified by:

isInverse in class Transformer

inverse

public Distorter inverse()

Description copied from class: Transformer

Get the inverse of the transformation. If the order matters, then the inverse is to be applied after the original transformation. This is primarily an issue with Converters.

Specified by:

inverse in class Distorter

transform

public void transform(double[] in,
                      double[] out)

Description copied from class: Transformer

Convert a single point where the output vector is supplied.

Specified by:

transform in class Transformer

Parameters:

in - The input vector.

out - The output vector, it may be the same as the input vector if the dimensionalities are the same. All transformers are expected to work with aliased inputs and output.

jacobian

public double[][] jacobian(double[] x)

Description copied from class: Distorter

Get the local Jacobian for the distortion. This implementation defers the calculation to the inverse distorter. Clearly this will need to be overriden in either the forward or backward distorter.

Overrides:

jacobian in class Distorter

Parameters:

x - The input position.

Returns:

The Jabobian matrix.
