Synthetic Face Datasets Generation via Latent Space Exploration from Brownian Identity Diffusion
David Geissbühler, Hatef Otroshi Shahreza, Sébastien Marcel
Face recognition models are trained on large-scale datasets, which have privacy and ethical concerns. Lately, the use of synthetic data to complement or replace genuine data for th…
- An Open Source Modular Platform for Contactless Hand Vascular Biometric Experiments
David Geissbühler, Sushil Bhattacharjee, Ketan Kotwal +2
Current finger-vein or palm-vein recognition systems usually require direct contact of the subject with the apparatus. This can be problematic in environments where hygiene is of p…
Exploring Double Field Theory
David Geissbuhler, Diego Marques, Carmen Nunez +1
We present a flux formulation of Double Field Theory, in which geometric and non-geometric fluxes are dynamical and field-dependent. Gauge consistency imposes a set of quadratic co…
Holographic Renormalization for z=2 Lifshitz Space-Times from AdS
Wissam Chemissany, David Geissbühler, Jelle Hartong +1
Lifshitz space-times with critical exponent z=2 can be obtained by dimensional reduction of Schroedinger space-times with critical exponent z=0. The latter space-times are asymptot…
