Abstract
AbstractA facial motion image synthesis method for intelligent man‐machine interface is examined. Here, the intelligent man‐machine interface is a kind of friendly man‐machine interface with voices and pictures in which human faces appear on a screen and answer questions, compared to the currently existing user interfaces which primarily uses letters. Thus what appears on the screen is human faces, and if speech mannerisms and facial expressions are natural, then the interactions with the machine are similar to those with actual human beings.To implement such an intelligent man‐machine interface it is necessary to synthesize natural facial expressions on the screen. This paper investigates a method to synthesize facial motion images based on given information on text and emotion. The proposed method utilizes the analysis‐synthesis image coding method. It constructs facial images by assigning intensity data to the parameters of a 3‐dimensional (3‐D) model matching the person in question. Moreover, it synthesizes facial expressions by modifying the 3‐D model according to the predetermined set of rules based on the input phonemes and emotion, and also synthesizes reasonably natural facial images.
