Caricatures from images

Abstract

A caricature is a graphical coding of facial features that seeks, paradoxically, to be more like the face than the face itself. A theory of computation for caricatures of frontal faces has been developed and implemented in computer graphics. The caricature generator starts with a digitized image of a face and distorts a line drawing representation of the face relative to a norm. This transformation emphasizes perceptually significant information, reduces noise, and exploits some of the same mechanisms used in human memory for faces.
