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 ... -
Facial expression modeling using component AAM models - Gaming applications
Bacivarov, Ioana; Corcoran, Peter (IEEE, 2009-10-23)In this paper we provide preliminary results on a new modeling approach for improved determination of facial expressions from a low-resolution video stream. An initial proof-of-concept using an extension of an Active ... -

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. ... -
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 ... -
Smart cameras: 2D affine models for determining subject facial expressions
Bacivarov, Ioana; Corcoran, Peter M.; Ionita, Mircea (IEEE, 2010-07-15)In this paper we consider how next generation of smart cameras will move beyond face detection and tracking to develop more useful analysis tools for determining the expressions and emotions of the subjects in images. An ... -
A statistical modeling based system for blink detection in digital cameras
Corcoran, Peter; Bacivarov, Ioana; Jonita, Mircea C (IEEE, 2008)In this paper we describe a system which uses statistical eye modeling to track the eyes and detect eyes blinking. The main challenge was to design an eye model robust to small variations of head pose and to extract the ... -
Statistical models of appearance for eye tracking and eye-blink detection and measurement
Bacivarov, Ioana; Ionita, Mircea; Corcoran, Peter (IEEE, 2008-08)A statistical Active Appearance Model (AAM) is developed to track and detect eye blinking. The model has been designed to be robust to variations of head pose or gaze. In particular we analyze and determine the model ...
