| Abstract(in English) | A considerable number of studies have been made on facial expression (FE) recognition techniques that are oriented to applications in pshycological and engineering fields. However, almost all of them are based on the extraction of movements of facial muscles in some local areas, which proves to be a difficult and costly task to perform in practise. In this paper, a new technique is proposed which is based on the use of the discrete cosine transform (DCT) of the whole facial image and a feedforward neural network. This technique is applied to a database consisting of samples of 60 persons, each having 5 normalized FE images. 40 person's FE images are used for training the network and 20 person's FE images are used for testing its generalization performance. As a result, the network gave 100% recognition rate for trained samples and maximum recognition rate of 95% for testing samples. |
