Emotion recognition using the shapes of the wrinkles

The emotion recognition has become a hot research topic in different domains: Human-Machine-Interaction, Natural Language processing etc. Recent research in the domain of Human Computer Interaction aims at recognizing the user's emotional state to give a smooth interface between humans and computers and to improve their interaction. In this paper we propose an emotion recognition system based on the analysis of the shapes of the wrinkles. The system contains four steps. The first one is detection of face's elements which is realized by the Viola and Jones detector. The second is localization of the wrinkles which is achieved automatically. Then, the information extraction. Finally, the classification using the wavelet network.
