Abstract
Video streams or images containing faces are essential to achieve intelligent, vision-based Human Machine Interaction (HMI). Specifically, being able to detect and track facial motion is of paramount importance in applications such as face-based people identification, expression analysis, surveillance and safety. In such a scenario, robustness to the real environment is repeatedly identified as one of the main issues that needs to be addressed. This thesis is concerned with the definition of a fully automatic 3D face tracking system robust to expression, illumination and occlusion. A fully automatic 3D face tracking system is typically constituted by three parts: i) face detection, ii) 3D model initialization (mask fitting), and iii) 3D deformable tracking. This thesis covers all of these three main aspects but concentrating the main contributions on the last two. Our major technique contributions are: i) Inclusion of morphing in the warping function of a constraint gradient-descent based template 3D tracking [...]
