apply

public float[] apply(float[] point)

Description copied from interface: CoordinateTransform

Apply the CoordinateTransform to a location.

Parameters:

point -

Returns:

transformed location

applyInPlace

public void applyInPlace(float[] point)

Description copied from interface: CoordinateTransform

Apply the CoordinateTransform to a location.

Parameters:

point -

applyInverse

public float[] applyInverse(float[] point)

Description copied from interface: InvertibleCoordinateTransform

Apply the inverse of the model to a point location

Parameters:

point -

Returns:

transformed point

applyInverseInPlace

public void applyInverseInPlace(float[] point)

Description copied from interface: InvertibleCoordinateTransform

Parameters:

point -

toString

public String toString()

Description copied from class: Model

Create a meaningful string representation of the model for save into text-files or display on terminals.

Specified by:

toString in class Model

fit

public final void fit(Collection<PointMatch> matches)
               throws NotEnoughDataPointsException

Description copied from class: Model

Fit the Model to a set of data points minimizing the global transfer error. This is assumed to be implemented as a least squares minimization. Use ransac and/ or Model.filter(Class, Collection, Collection) to remove outliers from your data points The estimated model transfers match.p2.local to match.p1.world.

Specified by:

fit in class Model

Parameters:

matches - set of point correpondences

Throws:

NotEnoughDataPointsException - an exception if matches does not contain enough data points

shake

public final void shake(Collection<PointMatch> matches,
 float scale,
 float[] center)

change the model a bit estimates the necessary amount of shaking for each single dimensional distance in the set of matches

Specified by:

shake in class Model

Parameters:

matches - point matches

scale - gives a multiplicative factor to each dimensional distance (scales the amount of shaking)

center - local pivot point for centered shakes (e.g. rotation)

clone

public TranslationModel3D clone()

Description copied from class: Model

Clone the model.

Specified by:

clone in class InvertibleModel
