Re-Nerfing: Improving Novel Views Synthesis through Novel Views Synthesis

no code implementations4 Dec 2023 Felix Tristram, Stefano Gasperini, Nassir Navab, Federico Tombari

With Re-Nerfing, we enhance the geometric consistency of novel views as follows: First, we train a NeRF with the available views.

VoxNeRF: Bridging Voxel Representation and Neural Radiance Fields for Enhanced Indoor View Synthesis

no code implementations9 Nov 2023 Sen Wang, Wei zhang, Stefano Gasperini, Shun-Cheng Wu, Nassir Navab

Creating high-quality view synthesis is essential for immersive applications but continues to be problematic, particularly in indoor environments and for real-time deployment.

3D Adversarial Augmentations for Robust Out-of-Domain Predictions

no code implementations29 Aug 2023 Alexander Lehner, Stefano Gasperini, Alvaro Marcos-Ramiro, Michael Schmidt, Nassir Navab, Benjamin Busam, Federico Tombari

We conduct extensive experiments across a variety of scenarios on data from KITTI, Waymo, and CrashD for 3D object detection, and on data from SemanticKITTI, Waymo, and nuScenes for 3D semantic segmentation.

Robust Monocular Depth Estimation under Challenging Conditions

no code implementations ICCV 2023 Stefano Gasperini, Nils Morbitzer, HyunJun Jung, Nassir Navab, Federico Tombari

While state-of-the-art monocular depth estimation approaches achieve impressive results in ideal settings, they are highly unreliable under challenging illumination and weather conditions, such as at nighttime or in the presence of rain.

Segmenting Known Objects and Unseen Unknowns without Prior Knowledge

no code implementations ICCV 2023 Stefano Gasperini, Alvaro Marcos-Ramiro, Michael Schmidt, Nassir Navab, Benjamin Busam, Federico Tombari

By doing so, for the first time in panoptic segmentation with unknown objects, our U3HS is trained without unknown categories, reducing assumptions and leaving the settings as unconstrained as in real-life scenarios.

R4Dyn: Exploring Radar for Self-Supervised Monocular Depth Estimation of Dynamic Scenes

no code implementations10 Aug 2021 Stefano Gasperini, Patrick Koch, Vinzenz Dallabetta, Nassir Navab, Benjamin Busam, Federico Tombari

While self-supervised monocular depth estimation in driving scenarios has achieved comparable performance to supervised approaches, violations of the static world assumption can still lead to erroneous depth predictions of traffic participants, posing a potential safety issue.

Panoster: End-to-end Panoptic Segmentation of LiDAR Point Clouds

no code implementations28 Oct 2020 Stefano Gasperini, Mohammad-Ali Nikouei Mahani, Alvaro Marcos-Ramiro, Nassir Navab, Federico Tombari

Panoptic segmentation has recently unified semantic and instance segmentation, previously addressed separately, thus taking a step further towards creating more comprehensive and efficient perception systems.
