Periodic orbits near collision in a restricted four-body problem for the eight choreography
Autor: Bengochea, Abimael, Burgos-García, Jaime, Pérez-Chavela, Ernesto
We study orbits near collision in a non-autonomous restricted planar four-body problem. This restricted problem consists of a massless particle moving under the gravitational influence due to three bodies following the figure-eight choreography. We u

Implicit Shape and Appearance Priors for Few-Shot Full Head Reconstruction
Autor: Caselles, Pol, Ramon, Eduard, Garcia, Jaime, Triginer, Gil, Moreno-Noguer, Francesc
Recent advancements in learning techniques that employ coordinate-based neural representations have yielded remarkable results in multi-view 3D reconstruction tasks. However, these approaches often require a substantial number of input views (typical

InstantAvatar: Efficient 3D Head Reconstruction via Surface Rendering
Autor: Canela, Antonio, Caselles, Pol, Malik, Ibrar, Ramon, Eduard, García, Jaime, Sánchez-Riera, Jordi, Triginer, Gil, Moreno-Noguer, Francesc
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 these techniques achieve an unprecedented accuracy, they take several mi

SIRA: Relightable Avatars from a Single Image
Autor: Caselles, Pol, Ramon, Eduard, Garcia, Jaime, Giro-i-Nieto, Xavier, Moreno-Noguer, Francesc, Triginer, Gil
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 solved. Methods based on 3D Morphable Models (3DMM), and their combina

The spatial Hill four-body problem I -- An exploration of basic invariant sets
Autor: Burgos-Garcia, Jaime, Bengochea, Abimael, Franco-Perez, Luis
In this work, we perform a first study of basic invariant sets of the spatial Hill's four-body problem, where we have used both analytical and numerical approaches. This system depends on a mass parameter mu in such a way that the classical Hill's pr
