Abstract:
1. One or more computer-readable media containing a program that is executable by a computer to create a three-dimensional model of a face, the program comprising the following actions: constructing a three-dimensional face model from two or more two-dimensional face images, wherein the constructed face model comprises a plurality of points specified in three dimensions; applying a combination of deformation vectors to a pre-specified face model to deform the pre-specified face model approximately to the constructed face model, wherein the pre-specified face model comprises a plurality points specified in three dimensions and each deformation vector specifies a plurality of displacements corresponding respectively to the plurality of points of the pre-specified face model; wherein the applying action comprises calculating a linear combination of the deformation vectors and the pre-specified face model, the actions further comprising; multiplying each deformation vector by a respective multiplicative constant before when calculating the linear combination; and selecting the multiplicative constants to minimize a summation of distances between the deformed face model and the points of the constructed face model.
