Facemorph
Class MultiscaleInterpolate

java.lang.Object
  Facemorph.MultiscaleInterpolate

public class MultiscaleInterpolate
extends java.lang.Object

Implements a multi-scale interpolation algorithm

Constructor Summary

MultiscaleInterpolate(int w, int h)
Creates a multi-scale warping object of the specified (equal input and output) dimensions

Method Summary

float	get(int x, int y) return the value of the warping function at the specified position
boolean	interpolate(FloatImage mask, FloatImage data) Interpolates the data using the mask to specify valid samples
boolean	interpolate(java.awt.geom.Point2D.Float[] source, float[] vals) Interpolates the given 2D values across the 2D space, by performing setup then calling interpolate()
float	sample(float x, float y) Sample from this interpolation

Constructor Detail

MultiscaleInterpolate

public MultiscaleInterpolate(int w,
                             int h)

Creates a multi-scale warping object of the specified (equal input and output) dimensions

Parameters:

w - The desired width

h - The desired height

Method Detail

interpolate

public boolean interpolate(FloatImage mask,
                           FloatImage data)

Interpolates the data using the mask to specify valid samples

Parameters:

mask - the mask specifies valid samples

data - the data specifies the interpolation constraints

Returns:

returns true if the interpolation is successful

interpolate

public boolean interpolate(java.awt.geom.Point2D.Float[] source,
                           float[] vals)

Interpolates the given 2D values across the 2D space, by performing setup then calling interpolate()

Parameters:

vals - the values of the interpolation constraints

source - The array of start point locations

Returns:

true of the interpolation was successful, false otherwise

get

public float get(int x,
                 int y)

return the value of the warping function at the specified position

Parameters:

x - The x-coordinate

y - The y-coordinate

Returns:

A float array of 2 containing the x and y value of the warp.

sample

public float sample(float x,
                    float y)

Sample from this interpolation

Parameters:

x - x-coord to sample at

y - y-coord to sample at

Returns:

the value of this function at (x,y)
