Facemorph
Class LinearWarp_1

java.lang.Object
  Facemorph.LinearWarp_1

public class LinearWarp_1
extends java.lang.Object

Performs triangulated linear interpolation for image warping

Constructor Summary

LinearWarp_1(int w, int h, int W, int H, boolean r)
Constructs a Linear warp with the input and output size specified

Method Summary

java.awt.Image	drawTess(java.awt.Image img) Draws the calculated triangulation on the image as a set of red lines, useful for testing the tesselation should already have been calculated e.g.
static void	main(java.lang.String[] args) Main function used for testing
java.awt.Image	warpImage(int n, java.awt.geom.Point2D.Float[] dest, java.awt.geom.Point2D.Float[] source, boolean borders, java.awt.Image inImage) Warps the input image from the shape specified by the source points to the shape specified by dest points
java.awt.Image	warpImage(Template t1, Template t2, boolean borders, java.awt.Image inImage) Warps inImage from shape t1 to shape t2

Method Detail

warpImage

public java.awt.Image warpImage(Template t1,
                                Template t2,
                                boolean borders,
                                java.awt.Image inImage)

Warps inImage from shape t1 to shape t2

Parameters:

t1 - Template specifying input shape

t2 - Template specifying output shape

borders - should the borders be pinned down, usually should be true

inImage - the input Image to warp

Returns:

Returns the warped image

warpImage

public java.awt.Image warpImage(int n,
                                java.awt.geom.Point2D.Float[] dest,
                                java.awt.geom.Point2D.Float[] source,
                                boolean borders,
                                java.awt.Image inImage)

Warps the input image from the shape specified by the source points to the shape specified by dest points

Parameters:

inImage - The input Image to warp

n - Number of input points to interpolate

dest - List of destination points to interpolate

source - List of source points to interpolate

borders - Indicates if the borders should be pinned down (using a set of points round the image edge)

Returns:

true if the interpolation was completed OK

drawTess

public java.awt.Image drawTess(java.awt.Image img)

Draws the calculated triangulation on the image as a set of red lines, useful for testing the tesselation should already have been calculated e.g. by a call to warpImage

Parameters:

img - The image to draw on

Returns:

returns an image with the triangulated points drawn on it

main

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

Main function used for testing

Parameters:

args - no parameters required
