Abstract

Emotion is a topic that has received much attention during the last few years, both in the context of speech synthesis, image understanding as well as in automatic speech recognition, interactive dialogues systems and wearable computing. This paper presents a formal model of a language (called Ekfrasis) as a software methodology that synthesizes (or generates) automatically various facial expressions by appropriately combining facial features. The main objective here is to use this methodology to generate various combinations of facial expressions and study if these combinations efficiently represent emotional behavioral patterns.
