Abstract :
Three-dimensional facial asymmetry is measured by constructing the 3D surface using a projected structured light pattern viewed by binocular stereo cameras. The projected pattern is a set of vertical bars with random breaks to resolve the stereo matching ambiguity. The facial symmetry plane is obtained by performing stochastic minimisation with an L(1) error norm on the depth asymmetries
