| Abstract(in English) | This paper presents an extraction method of facial expression rhythms, which are defined for time-series patterns created by changes of facial expressions and arousal levels caused by psychological stress levels, using individual facial expression charts focused on static diversity and dynamic diversity of faces. The proposal method consists of three steps: the first step is to create facial expression charts produced by arousal levels that is obtained by the results of hybrid learning of Self-Organizing Maps (SOM) and Fuzzy Adaptive Resonance Theory (ART) networks; the second step is to make codebooks using Fuzzy ARTMAP networks for modeling of facial expression spaces; and the third step is to extract facial expression rhythms using Hidden Markov Model (HMM) from time-serous patterns of facial expressions. We developed for an original facial expression dataset that consists of five male students and five female students from 18 through 22 years old at our university. We applied our method to the dataset and obtained the result of the state transitions to be estimated by HMM is extracted the rage of the facial expression changes. Moreover, we conformed the method can control the patterns of arousal levels in mixed facial expressions at the expressed process using the number of transition states on HMM. |
