The authors have been developing an evaluation method of facial expression in the previous reports. They demonstrated that facial expression can be quantitatively characterised by introducing the concept of the Fourier Descriptor (FD) and that the relationship between one's each individual facial factor such as an eye or a mouth and his/her psychological situation can be sufficiently expressed by the optimised discriminant analysis model. The present paper deals with overall evaluation of facial expression using the FDs of both eyes and mouth. The subjects were asked to exhibit the six fundamental emotions investigated in the field of psychology: happiness, surprise, fear, anger, disgust and sadness. The confidence level for each fundamental emotion was defined here as an individual evaluation of each facial factor. The multi-regression analysis was applied to relate facial expression to the six fundamental emotions and consequently contributions of each facial factor were obtained.
