Removing Adverse Volumetric Effects From Trained Neural Radiance Fields

no code implementations17 Nov 2023 Andreas L. Teigen, Mauhing Yip, Victor P. Hamran, Vegard Skui, Annette Stahl, Rudolf Mester

While the use of neural radiance fields (NeRFs) in different challenging settings has been explored, only very recently have there been any contributions that focus on the use of NeRF in foggy environments.

Realistic Full-Body Anonymization with Surface-Guided GANs

1 code implementation6 Jan 2022 Håkon Hukkelås, Morten Smebye, Rudolf Mester, Frank Lindseth

Recent work on image anonymization has shown that generative adversarial networks (GANs) can generate near-photorealistic faces to anonymize individuals.

Model-Based Parameter Optimization for Ground Texture Based Localization Methods

no code implementations3 Sep 2021 Jan Fabian Schmid, Stephan F. Simon, Rudolf Mester

A promising approach to accurate positioning of robots is ground texture based localization.

Urban Traffic Surveillance (UTS): A fully probabilistic 3D tracking approach based on 2D detections

no code implementations31 May 2021 Henry Bradler, Adrian Kretz, Rudolf Mester

We quantitatively evaluate UTS using self generated synthetic data and ground truth from the CARLA simulator, due to the non-existence of datasets with an urban vehicle surveillance setting and labeled 3D bounding boxes.

Mono-SF: Multi-View Geometry Meets Single-View Depth for Monocular Scene Flow Estimation of Dynamic Traffic Scenes

no code implementations ICCV 2019 Fabian Brickwedde, Steffen Abraham, Rudolf Mester

Existing 3D scene flow estimation methods provide the 3D geometry and 3D motion of a scene and gain a lot of interest, for example in the context of autonomous driving.

Mono-Stixels: Monocular depth reconstruction of dynamic street scenes

no code implementations7 Aug 2019 Fabian Brickwedde, Steffen Abraham, Rudolf Mester

In our experiments we use the public available DeepFlow for optical flow estimation and FCN8s for the semantic information as inputs and show on the KITTI 2015 dataset that mono-stixels provide a compact and reliable depth reconstruction of both the static and moving parts of the scene.

Joint Epipolar Tracking (JET): Simultaneous optimization of epipolar geometry and feature correspondences

no code implementations15 Mar 2017 Henry Bradler, Matthias Ochs, Rudolf Mester

In this paper, we propose a sparse direct method which introduces a loss function that allows to simultaneously optimize the unscaled relative pose, as well as the set of feature correspondences directly considering the image intensity values.

Learning Rank Reduced Interpolation with Principal Component Analysis

no code implementations15 Mar 2017 Matthias Ochs, Henry Bradler, Rudolf Mester

When facing situations with only very sparse measurements, typically the number of principal components is further reduced which results in a loss of expressiveness of the basis.
