A coarse-to-fine curvature analysis-based rotation invariant 3D face landmarking
Résumé
Automatic 2.5D face landmarking aims at locating
facial feature points on 2.5D face models, such as eye corners,
nose tip, etc. and has many applications ranging from face
registration to facial expression recognition. In this paper, we
propose a rotation invariant 2.5D face landmarking solution
based on facial curvature analysis combined with a generic
2.5D face model and make use of a coarse-to-fine strategy for
more accurate facial feature points localization. Experimented
on more than 1600 face models randomly selected from the
FRGC dataset, our technique displays, compared to a ground
truth from a manual 3D face landmarking, a 100% of good nose
tip localization in 8 mm precision and 100% of good localization
for the eye inner corner in 12 mm precision.
