Multimodal Web based system for human emotion recognition

The system being described in the paper presents a Web interface for a fully automatic audio-video human emotion recognition. The analysis is focused on the set of six basic emotions plus the neutral type. Different classifiers are involved in the process of face detection (AdaBoost), facial expression recognition (SVM and other models) and emotion recognition from speech (GentleBoost). The Active Appearance Model – AAM is used to get the information related to the shapes of the faces to be analyzed. The facial expression recognition is frame based and no temporal patterns of emotions are managed. The emotion recognition from movies is done separately on sound and video frames. The algorithm does not handle the dependencies between audio and video during the analysis. The methodologies for data processing are explained and specific performance measures for the emotion recognition are presented.
