Questionnaires about the comparison of expressive facial caricatures and expressionless ones are performed in order to obtain the parameter value change data for each facial expression. The parameter values transformation from an expressionless face to an expressive one is defined using these data for the addition of facial expressions. Expressive facial caricature drawings are evaluated subjectively and objectively. The validity of the process is discussed.
