Abstract

At this moment there is an ongoing project at Delft University of Technology aimed at the development of the Integrated System for Facial Expression Recognition (ISFER). The ISFER project is being developed in the Knowledge Based Systems group at the Faculty of Technical Mathematics and Informatics, TU Delft. In this project the works about image preprocessing, feature extraction and the interpretation of the results are bound in a single system. One of the most important parts of the facial expression recognition is recognizing the mouth expression. This paper describes a new approach to this task. Contrary to the works already done in this field, it is rather knowledge- than graphically-based. We use here the fuzzy-system and the artificial neural network techniques to obtain the desired results.
