RANRAC: Robust Neural Scene Representations via Random Ray Consensus

no code implementations15 Dec 2023 Benno Buschmann, Andreea Dogaru, Elmar Eisemann, Michael Weinmann, Bernhard Egger

We demonstrate the compatibility and potential of our solution for both photo-realistic robust multi-view reconstruction from real-world images based on neural radiance fields and for single-shot reconstruction based on light-field networks.

Neural inverse procedural modeling of knitting yarns from images

no code implementations1 Mar 2023 Elena Trunz, Jonathan Klein, Jan Müller, Lukas Bode, Ralf Sarlette, Michael Weinmann, Reinhard Klein

We investigate the capabilities of neural inverse procedural modeling to infer high-quality procedural yarn models with fiber-level details from single images of depicted yarn samples.

Efficient 3D Reconstruction, Streaming and Visualization of Static and Dynamic Scene Parts for Multi-client Live-telepresence in Large-scale Environments

no code implementations25 Nov 2022 Leif Van Holland, Patrick Stotko, Stefan Krumpen, Reinhard Klein, Michael Weinmann

Despite the impressive progress of telepresence systems for room-scale scenes with static and dynamic scene entities, expanding their capabilities to scenarios with larger dynamic environments beyond a fixed size of a few square-meters remains challenging.

Occlusion Fields: An Implicit Representation for Non-Line-of-Sight Surface Reconstruction

no code implementations16 Mar 2022 Javier Grau, Markus Plack, Patrick Haehn, Michael Weinmann, Matthias Hullin

Non-line-of-sight reconstruction (NLoS) is a novel indirect imaging modality that aims to recover objects or scene parts outside the field of view from measurements of light that is indirectly scattered off a directly visible, diffuse wall.

Spline-PINN: Approaching PDEs without Data using Fast, Physics-Informed Hermite-Spline CNNs

3 code implementations15 Sep 2021 Nils Wandel, Michael Weinmann, Michael Neidlin, Reinhard Klein

Second, convolutional neural networks provide fast inference and generalize but either require large amounts of training data or a physics-constrained loss based on finite differences that can lead to inaccuracies and discretization artifacts.

Physics-Informed Deep Learning of Incompressible Fluid Dynamics

no code implementations ICLR 2021 Nils Wandel, Michael Weinmann, Reinhard Klein

Moreover, the trained neural networks offer a differentiable update step to advance the fluid simulation in time and, thus, can be used as efficient differentiable fluid solvers.
