Robust face recognition using 2d and 3d data: Pose and illumination compensation
- …The paper addresses the problem of face recognition under varying pose and illumination. Robustness to appearance variations is achieved not only by using a combination of a 2D color and a 3D image of the face, but mainly by using face geometry information to cope with pose and illumination variatio…

Robust real-time 3D head pose estimation from range data
- …In this paper a real-time 3D pose estimation algorithm using range data is described. The system relies on a novel 3D sensor that generates a dense range image of the scene. By not relying on brightness information, the proposed system guarantees robustness under a vari-ety of illumination condition…

Pose And Illumination Compensation For 3D Face Recognition
- …The paper describes a face recognition system using a combination of color and depth images. To cope with illumination and pose variations 3D information is used for the normalization of the input images. The proposed pose compensation algorithm is based on a robust 3D face detection and pose estima…

Expression Compensation for Face Recognition Using a Polar Geodesic Representation
- …This paper addresses the problem of face recognition in the presence of deformation due to expressions. Facial motion is considered as an isometric mapping between surfaces, which allows preservation of geodesic distance between facial points. Subject to this assumption, we propose a novel technique…

3D FACIAL EXPRESSION RECOGNITION USING SWARM INTELLIGENCE
- …In this paper, we present a novel approach for 3D facial expression recognition which is inspired by the advances of ant colony and particle swarm optimization (ACO and PSO respectively) in the field of data mining. Anatomical correspondence between faces is first established using a generic 3D face…

Motion Estimation based on Spatio-temporal Warping for Very Low Bit-Rate Coding
- …In this paper a motion estimation algorithm is presented, based on spatio-temporal warping of an image sequence. The motion field function is modeled by isoparametric cubic finite elements, depending on a set of elementary displacement vectors. A model refinement scheme is proposed for the adaptivel…
