In the PICASSO system, a facial caricaturing system, some visual illusions such as the Wundt-Fick illusion and the Ponzo illusion for example, are applied to evaluate the shapes of the facial parts such as eyebrows, nose, mouth and face contour, in the deformation process of caricature generation. In many cases, as well-deformed caricatures are evaluated to be successful, it is confirmed that the utilization of the visual illusion is effective to evaluate the results of caricatures. In this paper, the models of mathematical expressions of visual illusions are presented together with the results of human experiments. And, a method to apply visual illusions and to control the exaggeration process is proposed.
