Image synthesis by illuminating a virtual deviation-mapped surface

A computer-implemented method of synthesizing an image from at least two other images comprising:

• defining a plurality of normals relative to a surface that represents a first image;
• angularly adjusting individual normals by an amount that is a function of the intensity of individual corresponding portions of a second image to provide an intermediate surface;
• and
• applying an illumination model to the intermediate surface to provide a resultant synthesized image.
