This article addresses the issue of expressive face modelling using an active appearance model for facial expression recognition and synthesis. We consider the six universal emotional categories namely joy, anger, fear, disgust, sadness and surprise. After a description of the active appearance model (computed with 3 or only one PCA), we address the active(More)
Facial expression interpretation, recognition and analysis is a key issue in visual communication and man to machine interaction. We address the issues of facial expression recognition and synthesis and compare the proposed bilinear factorization based representations with previously investigated methods such as linear discriminant analysis and linear(More)
This paper addresses the issue of lip tracking and cloning using appearance models. In this perspective, a statistical color-based lip detector is first used to classify the pixels of an image into lip and non-lip pixels. This rough estimation of the lip position is then used to initialize an appearance model. This models convergence allows to refine the(More)
Facial expression interpretation, recognition and analysis is a key issue in visual communication and man to machine interaction. In this paper, we present a technique for extracting appearance parameters from a natural image or video sequence, which allow reproduction of natural looking expressive synthetic faces. This technique was used to perform face(More)

We are living in the 21st century , As the technology grows the security issues are gradually increasing and for those issues there is always a need for improvements in existing methods or there is a hope for new ideas towards this field. As we use the technology from everywhere in over daily life there is a challenge comes regarding data security or(More)
Verification of identity is commonly achieved by looking at the face of a person and listening to his (her) speech. Automatic means of achieving this verification has been studied for several decades. Indeed, a talking face offers many features to achieve a robust verification of identity. The current deployment of videophones drives new opportunities for a(More)
