Inverse Neural Rendering for Explainable Multi-Object Tracking

no code implementations18 Apr 2024 Julian Ost, Tanushree Banerjee, Mario Bijelic, Felix Heide

We propose to recast 3D multi-object tracking from RGB cameras as an \emph{Inverse Rendering (IR)} problem, by optimizing via a differentiable rendering pipeline over the latent space of pre-trained 3D object representations and retrieve the latents that best represent object instances in a given input image.

Thin On-Sensor Nanophotonic Array Cameras

no code implementations5 Aug 2023 PRANEETH CHAKRAVARTHULA, Jipeng Sun, Xiao Li, Chenyang Lei, Gene Chou, Mario Bijelic, Johannes Froesch, Arka Majumdar, Felix Heide

The optical array is embedded on a metasurface that, at 700~nm height, is flat and sits on the sensor cover glass at 2. 5~mm focal distance from the sensor.

ScatterNeRF: Seeing Through Fog with Physically-Based Inverse Neural Rendering

no code implementations ICCV 2023 Andrea Ramazzina, Mario Bijelic, Stefanie Walz, Alessandro Sanvito, Dominik Scheuble, Felix Heide

With data as bottleneck and most of today's training data relying on good weather conditions with inclement weather as outlier, we rely on an inverse rendering approach to reconstruct the scene content.

LiDAR-in-the-Loop Hyperparameter Optimization

no code implementations CVPR 2023 Félix Goudreault, Dominik Scheuble, Mario Bijelic, Nicolas Robidoux, Felix Heide

The resulting point clouds output by these DSPs are input to downstream 3D vision models -- both, in the form of training datasets or as input at inference time.

Simulating Road Spray Effects in Automotive Lidar Sensor Models

1 code implementation16 Dec 2022 Clemens Linnhoff, Dominik Scheuble, Mario Bijelic, Lukas Elster, Philipp Rosenberger, Werner Ritter, Dengxin Dai, Hermann Winner

The model conforms to the Open Simulation Interface (OSI) standard and is based on the formation of detection clusters within a spray plume.

LiDAR Snowfall Simulation for Robust 3D Object Detection

1 code implementation CVPR 2022 Martin Hahner, Christos Sakaridis, Mario Bijelic, Felix Heide, Fisher Yu, Dengxin Dai, Luc van Gool

Due to the difficulty of collecting and annotating training data in this setting, we propose a physically based method to simulate the effect of snowfall on real clear-weather LiDAR point clouds.

Gated2Gated: Self-Supervised Depth Estimation from Gated Images

1 code implementation CVPR 2022 Amanpreet Walia, Stefanie Walz, Mario Bijelic, Fahim Mannan, Frank Julca-Aguilar, Michael Langer, Werner Ritter, Felix Heide

Gated cameras hold promise as an alternative to scanning LiDAR sensors with high-resolution 3D depth that is robust to back-scatter in fog, snow, and rain.

A Benchmark for Spray from Nearby Cutting Vehicles

no code implementations24 Aug 2021 Stefanie Walz, Mario Bijelic, Florian Kraus, Werner Ritter, Martin Simon, Igor Doric

Current driver assistance systems and autonomous driving stacks are limited to well-defined environment conditions and geo fenced areas.

ZeroScatter: Domain Transfer for Long Distance Imaging and Vision through Scattering Media

1 code implementation CVPR 2021 Zheng Shi, Ethan Tseng, Mario Bijelic, Werner Ritter, Felix Heide

Most of today's supervised imaging and vision approaches, however, rely on training data collected in the real world that is biased towards good weather conditions, with dense fog, snow, and heavy rain as outliers in these datasets.

Benchmarking Image Sensors Under Adverse Weather Conditions for Autonomous Driving

no code implementations6 Dec 2019 Mario Bijelic, Tobias Gruber, Werner Ritter

Adverse weather conditions are very challenging for autonomous driving because most of the state-of-the-art sensors stop working reliably under these conditions.

Pixel-Accurate Depth Evaluation in Realistic Driving Scenarios

1 code implementation21 Jun 2019 Tobias Gruber, Mario Bijelic, Felix Heide, Werner Ritter, Klaus Dietmayer

This work introduces an evaluation benchmark for depth estimation and completion using high-resolution depth measurements with angular resolution of up to 25" (arcsecond), akin to a 50 megapixel camera with per-pixel depth available.

Seeing Through Fog Without Seeing Fog: Deep Multimodal Sensor Fusion in Unseen Adverse Weather

1 code implementation CVPR 2020 Mario Bijelic, Tobias Gruber, Fahim Mannan, Florian Kraus, Werner Ritter, Klaus Dietmayer, Felix Heide

The fusion of multimodal sensor streams, such as camera, lidar, and radar measurements, plays a critical role in object detection for autonomous vehicles, which base their decision making on these inputs.

Suppression of topological Mott-Hubbard phases by multiple charge orders in the honeycomb extended Hubbard model

no code implementations30 Dec 2017 Mario Bijelic, Ryui Kaneko, Claudius Gros, Roser Valentí

We investigate the competition between charge-density-wave (CDW) states and a Coulomb interaction-driven topological Mott insulator (TMI) in the honeycomb extended Hubbard model.
