Can Shadows Reveal Biometric Information?

We transfer what we learn from the synthetic data to the real data using domain adaptation in a completely unsupervised way.

Identity-Expression Ambiguity in 3D Morphable Face Models

no code implementations29 Sep 2021 Bernhard Egger, Skylar Sutherland, Safa C. Medin, Joshua Tenenbaum

We demonstrate that non-orthogonality of the variation in identity and expression can cause identity-expression ambiguity in 3D Morphable Models, and that in practice expression and identity are far from orthogonal and can explain each other surprisingly well.

Beyond Binomial and Negative Binomial: Adaptation in Bernoulli Parameter Estimation

no code implementations24 Sep 2018 Safa C. Medin, John Murray-Bruce, David Castañón, Vivek K Goyal

Estimating the parameter of a Bernoulli process arises in many applications, including photon-efficient active imaging where each illumination period is regarded as a single Bernoulli trial.
