Three-Dimensional Face Caricaturing by Anthropometric Distortions
Roberto Cesar Cavalcante Vieira, Creto Augusto Vidal, Joaquim Bento Cavalcante-Neto · 2013
Caricatures are models of persons or things in which certain striking characteristics are exaggerated in order to create a comic or grotesque effect. This paper is concerned with a strategy for automatically generating caricatures of threedimensional models based on anthropometric measures and geometric manipulations by influence zones. In the proposed strategy, measures from a reference model serve as means of comparison with the corresponding measures in the model to be caricatured. Deformations are applied to the features that differ most from the corresponding features in the reference model. This method is independent of mesh topology. Unlike other techniques, it is possible to generate variations of caricatures, adopting different sequences of deformations, application of asymmetry and expressions. Our method also does not need 3D model databases to be used as a base of combinations or comparisons of models.
