A Study of Facial Expression Transfer Method to 3D Characters Using Regression Analysis

Abstract

We propose a method to recognize human facial expressions and reproduce 3D characters expressive enough for live entertainment. We conducted a questionnaire survey on the facial expressions of 3D avatars created based on the proposed method, and compared the difference between the assumed facial expressions and those actually guessed. Positive expressions were relatively well conveyed, but negative emotions were not. Although the proposed method was able to extract the expressions prepared for 3D characters, it was insufficient in expressing rich emotions.
