                                       java.awt.image.ImageObserver ob)

Transforms subjectImage using the prototypes given and returns the result. The transformed Template is returned in newTemplate. The transformation follows the formula: new = subject + s*(dest-source)

Parameters:

subjectTemplate - The Template outlining the features of subjectImg

sourceTemplate - The (average) Template outlining the features of sourceImg

destTemplate - The (average) Template outlining the features of destImg

newTemplate - Template to hold the Template corresponding to the transformed result. Useful for morphing afterwards.

subjectImg - The Image to transform

sourceImg - The (average) image of the source group

destImg - The (average) image of the destination group

s - The amount to scale this transform by. 0 = no transform, 1= complete transform.

ob - An ImageObserver used for obtaining Image sizes

Returns:

The transformed image.
