Implicit Shape and Appearance Priors for Few-Shot Full Head Reconstruction
Pol Caselles, Eduard Ramon, Jaime Garcia +2
Recent advancements in learning techniques that employ coordinate-based neural representations have yielded remarkable results in multi-view 3D reconstruction tasks. However, these…
InstantAvatar: Efficient 3D Head Reconstruction via Surface Rendering
Antonio Canela, Pol Caselles, Ibrar Malik +5
Recent advances in full-head reconstruction have been obtained by optimizing a neural field through differentiable surface or volume rendering to represent a single scene. While th…
Photorealistic Facial Wrinkles Removal
Marcelo Sanchez, Gil Triginer, Coloma Ballester +2
Editing and retouching facial attributes is a complex task that usually requires human artists to obtain photo-realistic results. Its applications are numerous and can be found in…
SIRA: Relightable Avatars from a Single Image
Pol Caselles, Eduard Ramon, Jaime Garcia +3
Recovering the geometry of a human head from a single image, while factorizing the materials and illumination is a severely ill-posed problem that requires prior information to be…
H3D-Net: Few-Shot High-Fidelity 3D Head Reconstruction
Eduard Ramon, Gil Triginer, Janna Escur +4
Recent learning approaches that implicitly represent surface geometry using coordinate-based neural representations have shown impressive results in the problem of multi-view 3D re…
Understanding high gain twin beam sources using cascaded stimulated emission
Gil Triginer, Mihai D. Vidrighin, Nicolás Quesada +5
We present a new method for the spectral characterization of pulsed twin beam sources in the high gain regime, using cascaded stimulated emission. We show an implementation of this…
Theory of high-gain twin-beam generation in waveguides: from Maxwell's equations to efficient simulation
Nicolás Quesada, Gil Triginer, Mihai D. Vidrighin +1
We provide an efficient method for the calculation of high-gain, twin-beam generation in waveguides derived from a canonical treatment of Maxwell's equations. Equations of motion a…
Efficient algorithm for boson sampling with partially distinguishable photons
Jelmer J. Renema, Adrian Menssen, William R. Clements +3
We demonstrate how boson sampling with photons of partial distinguishability can be expressed in terms of interference of fewer photons. We use this observation to propose a classi…
Quantum atom-light interfaces in the gaussian description for spin-1 systems
Giorgio Colangelo, Robert J. Sewell, Naeimeh Behbood +2
We extend the covariance-matrix description of atom--light quantum interfaces, originally developed for real and effective spin-1/2 atoms, to include "spin alignment" degrees of fr…
