This paper is organized as follow. We describe the image databases in Section 2 and the features used for emotion recognition in Section 3. The classification process is explained in Section 4. In Section 5 we summarize our results. We conclude about our study and provide some perspectives in Section 6.

Image databases In the domain of emotion extraction, the choice of the database is not trivial since there is no reference for all emotion studies and applications, some authors even built their own dataset without spreading it. We choose in this study to considered two databases: the first one is composed of low seman...

1, there are images with blood, dirt, high semantic photomanipulations or naked people which might induce a bias in the assessment of the images. There is a risk of overreaction to neutral images viewed right after strong pleasant or unpleasant ones. Our aim in this paper is to evaluate the behaviour of our strategy de...
