PermutoSDF: Fast Multi-View Reconstruction with Implicit Surfaces using Permutohedral Lattices

1 code implementation CVPR 2023 Radu Alexandru Rosu, Sven Behnke

We propose improvements to the two areas by replacing the voxel hash encoding with a permutohedral lattice which optimizes faster, especially for higher dimensions.

Neural Strands: Learning Hair Geometry and Appearance from Multi-View Images

no code implementations28 Jul 2022 Radu Alexandru Rosu, Shunsuke Saito, Ziyan Wang, Chenglei Wu, Sven Behnke, Giljoo Nam

Furthermore, we introduce a novel neural rendering framework based on rasterization of the learned hair strands.

Abstract Flow for Temporal Semantic Segmentation on the Permutohedral Lattice

1 code implementation29 Mar 2022 Peer Schütt, Radu Alexandru Rosu, Sven Behnke

Semantic segmentation is a core ability required by autonomous agents, as being able to distinguish which parts of the scene belong to which object class is crucial for navigation and interaction with the environment.

NeuralMVS: Bridging Multi-View Stereo and Novel View Synthesis

1 code implementation9 Aug 2021 Radu Alexandru Rosu, Sven Behnke

Our method uses only a sparse set of images as input and can generalize well to novel scenes.

Beyond Photometric Consistency: Gradient-based Dissimilarity for Improving Visual Odometry and Stereo Matching

no code implementations8 Apr 2020 Jan Quenzel, Radu Alexandru Rosu, Thomas Läbe, Cyrill Stachniss, Sven Behnke

We integrate both into stereo estimation as well as visual odometry systems and show clear benefits for typical disparity and direct image registration tasks when using our proposed metric.

Bonn Activity Maps: Dataset Description

no code implementations13 Dec 2019 Julian Tanke, Oh-Hun Kwon, Patrick Stotko, Radu Alexandru Rosu, Michael Weinmann, Hassan Errami, Sven Behnke, Maren Bennewitz, Reinhard Klein, Andreas Weber, Angela Yao, Juergen Gall

The key prerequisite for accessing the huge potential of current machine learning techniques is the availability of large databases that capture the complex relations of interest.

Semi-Supervised Semantic Mapping through Label Propagation with Semantic Texture Meshes

no code implementations17 Jun 2019 Radu Alexandru Rosu, Jan Quenzel, Sven Behnke

We propose to represent the semantic map as a geometrical mesh and a semantic texture coupled at independent resolution.
