Abstract
In the past few years, 3D face modeling has gained
significant attention. Reliable modeling of the face is
necessary for good performance of a 3D assisted face
recognition system. In this paper, we model 3D human
face from binocular stereo images. The stereo
matching problem has been formulated as an energy
minimization problem that progressively propagates
depth from reliable regions to unreliable regions by an
annealing scheme. The concept of smooth 2D grid is
used to enable regularizing the final depth solution. In
the energy equation, area based matching is used for
the data term. The smoothness term relies on
annealing. The 2D grid facilitates the estimation of the
