Abstract

In this paper a system is described for the automatic generation ofa speciﬁc semantic 3D model of a human face from a recorded stereoscopic image sequence. In the acquisition stage a calibrated stereoscopic camera records the speciﬁc face. After rectification of the image sequences a dense disparity ﬁeld is estimated using a Markov Random Field approach. Next a triangle based 3D-wire frame model of the speciﬁc face is reconstructed by triangulation of corresponding left and right pixels. After compensation for rotation and translation, a triangle based 3D-wire frame model of a generic face is elastically matched to the speciﬁc face. As a consequence of this approach the resulting 3D model accurately represents the geometry of the subject with the availability of the face semantic information which is required for realistic representation and animation of human faces as well as for accurate facial expressions estimation.
