Detection and expression classification systems for face images (FADECS)

Towards building new, friendlier human-computer interaction systems and multimedia interactive services systems, we developed a neural network-based image processing system (called FADECS), which first determines automatically whether or not there are any faces in given images and, if so, returns the location and extent of each face. Next, FADECS uses neural network-based classifiers which allow the classification of several facial expressions from features that we develop and describe.
