Computerized Facial Caricature Modeled on the Drawing Style and Emphasis Technique by Caricaturist

Abstract

In this paper we aim to apply the drawing methods of caricature artist to the synthesis of facial caricatures by computer. Caricature artist modifies the drawing styles and the way of emphasis depending on facial features of individual person. The characteristics in drawing methods of caricature artist are treated numerically by applying principal component analysis to shapes and arrangement of facial parts in caricatures drawn by artist. The general framework of the face recognition by humans and techniques of caricature artist are also considered to reflect the facial features of an individual more effectively to caricatures. Facial caricatures drawn by the proposed method are compared to those by the previous method to show its usefulness.
