Class ThinPlateSplineInterpolation

java.lang.Object

edu.stanford.rsl.tutorial.motionEstimation.ThinPlateSplineInterpolation

public class ThinPlateSplineInterpolation
extends java.lang.Object

This class provides methods to interpolate scattered data of any dimension using a thin plate spline. The kernel is correct for 3-D. Other dimensions will require a different kernel, e.g. r*r*ln(r) for 2-D

Constructor Detail

ThinPlateSplineInterpolation

public ThinPlateSplineInterpolation(int dimension,
                            java.util.ArrayList<PointND> points,
                            java.util.ArrayList<PointND> values)

Method Detail

getAsFloatPoints

public float[] getAsFloatPoints()

getAsFloatA

public float[] getAsFloatA()

getAsFloatB

public float[] getAsFloatB()

getAsFloatCoeffs

public float[] getAsFloatCoeffs()

setNewPointsAndRecalibrate

public void setNewPointsAndRecalibrate(java.util.ArrayList<PointND> points,
                              java.util.ArrayList<PointND> values,
                              int dimension)

This method accepts a new pointgrid for interpolation, and the corresponding values. It automatically re-estimates the interpolation coefficients

Parameters:

points - Interpolation grid

values - corresponding values for the points

dimension - Dimension

interpolate

public SimpleVector interpolate(PointND pt)

Interpolation function

Parameters:

pt - point at which the value should be interpolated

Returns:

value

main

public static void main(java.lang.String[] args)
