[Special Effects] Photometric-Stereo DL : 0: cvpr2012_oral A Closed-Form Solution to Uncalibrated Photometric Stereo via Diffuse Maxima-In this paper we propose a novel solution to uncalibrated photometric stereo. Our approach is to eliminate the socalled generalized bas relief (GBR) ambiguity by exploiting points where the Lambertian reflection is maximal. We demonstrate several noteworthy properties of these maxima: 1) Closed-form solution: A single diffuse maximum constrains the GBR ambiguity to a semi-circle in 3D space 2) Efficiency: As few as two diffuse maxima in different images identify a unique solution 3) GBR-invariance: The estimation error of the GBR parameters is completely independent of the true parameters. Furthermore, our algorithm is remarkably robust: It can obtain an accurate estimate of the GBR parameters even with extremely high levels of outliers in the detected maxima (up to 80 of the observations). The method is validated on real data and achieves state-of-the-art results.

[Industry research] FACE3D-Series DL : 0: Abstract—Recently, a 3D face recognition approach based on geometric invariant signatures, has been proposed. The key idea of the algorithm is a representation of the facial surface, invariant to isometric deformations, such as those resulting from facial expressions. One of the crucial stages in the construction of the geometric invariants is the measurement of geodesic distances on triangulated surfaces, carried out by fast marching on triangulated domains (FMTD). Proposed here is a method, which uses only the metric tensor of the surface for geodesic distance computation. When combined with photometric stereo used for facial surface acquisition, it allows constructing a bending- invariant representation of the face without reconstructing the 3D surface. - Abstract—Recently, a 3D face recognition approach based on geometric invariant signatures, has been proposed.
