Recursive Head Reconstruction from Multi-View Video Sequences
Résumé
Face reconstruction from images has been a core topic for the last decades, and is now involved in many
applications such as identity verification or human–computer interaction. The 3D Morphable Model
introduced by Blanz and Vetter has been widely used to this end, because its specific 3D modeling offers
robustness to pose variation and adaptability to the specificities of each face.
To overcome the limitations of methods using a single image, and since video has become more and
more affordable, we propose a new method which exploits video sequences to consolidate the 3D head
shape estimation using successive frames. Based on particle filtering, our algorithm updates the model
estimation at each instant and it is robust to noisy observations. A comparison with the Levenberg–
Marquardt global optimization approach on various sets of data shows visual improvements both on pose
and shape estimation. Biometric performances confirm this trend with a mean reduction of 10% in terms
of False Rejection Rate.
