Joint Reconstruction and Spatial Super-Resolution of Hyper-Spectral CTIS Images via Multi-Scale Refinement

1 code implementation IEEE TRANSACTIONS ON COMPUTATIONAL IMAGING 2024 Mazen Mel, Alexander Gatto, Pietro Zanuttigh

Furthermore, we introduce HSIRS, the largest dataset of its kind for joint spectral image reconstruction and semantic segmentation of food items with high quality manually annotated segmentation maps and we showcase how hyper-spectral data allows to efficiently tackle this task.

NeISF: Neural Incident Stokes Field for Geometry and Material Estimation

no code implementations CVPR 2024 Chenhao Li, Taishi Ono, Takeshi Uemori, Hajime Mihara, Alexander Gatto, Hajime Nagahara, Yusuke Moriuchi

To address this problem, we propose Neural Incident Stokes Fields (NeISF), a multi-view inverse rendering framework that reduces ambiguities using polarization cues.

Inverse Rendering

Heterogeneous Light Fields

no code implementations CVPR 2016 Maximilian Diebold, Bernd Jahne, Alexander Gatto

In contrast to traditional binocular or multi-view stereo approaches, the adequately sampled space of observations in light-field imaging allows, to obtain dense and high quality depth maps.
