On autonomous control method for facial caricature generation based on a model of visual illusion-experimental modeling of visual illusion

Summary form only given as follows. In the PICASSO system, a facial caricaturing system, some visual illusions are applied to evaluate the shapes of the facial parts 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 the paper, the models of mathematical expressions of visual illusions are presented together with the results of human experiments. A method to apply visual illusions and to control the exaggeration process is proposed.
