Summary: 
In the PICASSO, a system for the facial caricature generation, as the basic mechanisms to extract the individuality features of faces and to deform the features have been already introduced, it is expected to realize an autonomous mechanism to evaluate facial caricatures. The evaluation should be based on the framework of human visual cognition. In the PICASSO, 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. 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, some experimental results are presented together with the definition of the evaluation measures and the further subjects.
