Influence of Self-Face in Preference Judgment for the Face by Physical Feature of Face

Abstract

In the medical field, inspection systems using the face have been utilized. However, in such a system, it is possible that the combination of a patient’s preference and presentation face image will greatly affect the test results. Therefore, it is important to analyze the various factors that affect the impression of the face. Previous studies report many preference factors that are common among subjects. In this study, we analyze preference factors that are different for each subject by evaluating Japanese faces in the hedonic dimension. We focus on the face of the subject’s own face is one of these and perform a quantitative analysis using six features of the eyes, mouth, and nose. In addition, we perform a quantitative analysis using six features of the eyes, mouth, and nose. The experimental results show that it is important to focus on the similarity between a subject’s eyes in a positive face and their eyes in a negative face. Moreover, we analyze the relationship between degree of preference and facial expression recognition using the effective index of the self-face. As a result, we suggest that faces with eyes that are similar to the self-face are evaluated positively in the expression recognition.
