Appearance capturing and animation techniques for realistic, true-identity gaming avatars
Ionita, Mircea C.; Corcoran, Peter (IEEE, 2009-10-23)Making use of a class of 2D statistical face models known as active appearance models (AAMs), we investigate a technique for generating real-time animated avatars suitable for video gaming. We consider here a number of ... -
A combined approach to feature extraction for mouth characterization and tracking
Bacivarov, Ioana; Ionita, Mircea C.; Corcoran, Peter (IEEE, 2009-02-10)A statistical Active Appearance Model (AAM) is developed to model and track the lips. A major challenge in modelling the mouth area, considered the most deformable facial feature, is the weak contrast between lips and skin ... -
Enhanced real-time face models from stereo imaging for gaming applications
Ionita, Mircea C.; Andorko, Istvan; Corcoran, Peter (IEEE, 2009-10-23)Techniques for improved 2D active appearance face models are presented. When these are applied to stereoscopic image pairs we show that sufficient information on image depth is obtained to generate an approximate 3D face ... -
Next Generation Face Tracking Technology Using AAM Techniques
Corcoran, Peter; Ionita, Mircea C.; Bacivarov, Ioana (IEEE, 2007)This paper realizes an investigation of the active appearance model (AAM) techniques, with particular emphasis on problems related to the implementation of AAM in realtime face tracking applications for embedded systems. ... -
On color texture normalization for active appearance models
Ionita, Mircea C.; Corcoran, Peter M.; Buzuloiu, Vasile (IEEE, 2009-05-12)The extension of the standard grayscale active appearance model (AAM) techniques to color images is investigated. Prior work in this field has mainly focused on RGB color models which did not demonstrate noticeable benefits ... -
Separating Directional Lighting Variability in Statistical Face Modelling Based on Texture Space Decomposition
Ionita, Mircea C.; Bacivarov, Ioana; Corcoran, Peter (IEEE, 2007-07-04)In this paper we propose a simple method for decomposing the linear texture space of a facial appearance model into two linear subspaces, one for inter-individual variability and another for variations caused by directional ...
