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…
