Abstract
This paper presents a framework for a customizable MPEG-4 face
player using a FAPs (Facial Animation Parameters) sequence recovered
from a real-time image sequence. First, the 3D nonrigid motion and
structure of the facial features is recovered from a 2D image sequence
and a “person-specific” model of the face. The model
consists of the intensity and range image of the face. Then, the FAPs
are computed from the recovered 3D structure. The customizable MPEG4
face animation is generated using a FAP sequence and a model of a
specific person. The dataset of four face image sequences from three
different face orientations equipped with range images are used. The GT
(ground truth) results are generated using the 3D structure provided by
range images. The results are evaluated quantitatively by comparing
recovered FAP values, and qualitatively by comparing the generated
MPEG-4 animations. FAPs are recovered up to 8% (relative) and 16 FAP
units (absolute) accuracy and the animation is nearly identical to the
MPEG-4 animation using GT FAPs
