Bio

I am a PhD candidate in the Visual Computing Lab since 2021. My interest is in 3D reconstruction and neural rendering. From 2016-2021, I was developing software for autonomous driving at BMW, focusing on localization and sensor fusion. I studied computer science (M.Sc.) and electrical engineering (B.Eng.) at the Universities of Applied Sciences in Ulm and Esslingen. My master thesis was on vehicle localization in 6 degrees of freedom for augmented reality. During my studies, I was active in a RoboCup Team and I spent a semester at Hacettepe University in Ankara, Turkey, as part of the Erasmus program.

Research Interest

Neural rendering, 3D reconstruction, novel view synthesis

Publications

L3DG: Latent 3D Gaussian Diffusion
Barbara Rössle, Norman Müller, Lorenzo Porzi, Samuel Rota Bulò, Peter Kontschieder, Angela Dai, Matthias Nießner
SIGGRAPH Asia 2024
L3DG proposes generative modeling of 3D Gaussians using a learned latent space. This substantially reduces the complexity of the costly diffusion generation process, allowing higher detail on object-level generation, and scalability to room-scale scenes.

GANeRF: Leveraging Discriminators to Optimize Neural Radiance Fields
Barbara Rössle, Norman Müller, Lorenzo Porzi, Samuel Rota Bulò, Peter Kontschieder, Matthias Nießner
SIGGRAPH Asia 2023
GANeRF proposes an adversarial formulation whose gradients provide feedback for a 3D-consistent neural radiance field representation. This introduces additional constraints that enable more realistic novel view synthesis.

End2End Multi-View Feature Matching with Differentiable Pose Optimization
Barbara Rössle, Matthias Nießner
ICCV 2023
End2End Multi-View Feature Matching connects feature matching and pose optimization in an end-to-end trainable approach that enables matches and confidences to be informed by the pose estimation objective. We introduce GNN-based multi-view matching to predict matches and confidences tailored to a differentiable pose solver, which significantly improves pose estimation performance.

Dense Depth Priors for Neural Radiance Fields from Sparse Input Views
Barbara Rössle, Jonathan T. Barron, Ben Mildenhall, Pratul P. Srinivasan, Matthias Nießner
CVPR 2022
We leverage dense depth priors for recovering neural radiance fields (NeRF) of complete rooms when only a handful of input images are available. First, we take advantage of the sparse depth that is freely available from the structure from motion preprocessing. Second, we use depth completion to convert these sparse points into dense depth maps and uncertainty estimates, which are used to guide NeRF optimization.
