We present a model for the lips using the Active Shape Model (ASM) based on B?ezier Curves which can capture the dynamics of the lips efficiently. The curves are defined only by a...
In this paper we present an approach for lip motion analysis that can be used in conjunction with a person authentication system based on face recognition, to avoid attacks on the...

The ability to detect and track human heads and faces in video sequences is useful in a great number of applications, such as human-computer interaction and gesture recognition. Re...
Lip tracking is crucial to the success of a lipreading recognition system. This paper presents a robust lip tracking algorithm using localized color active contours and deformable...
Abstract. We present a lip contour tracking algorithm using attractorguided particle filtering. Usually it is difficult to robustly track the lip contour because the lip contour i...
