Improved Semantic Stixels via Multimodal Sensor Fusion

no code implementations24 Sep 2018 Florian Piewak, Peter Pinggera, Markus Enzweiler, David Pfeiffer, Marius Zöllner

Our results indicate that the proposed mid-level fusion of LiDAR and camera data improves both the geometric and semantic accuracy of the Stixel model significantly while reducing the computational overhead as well as the amount of generated data in comparison to using a single modality on its own.

Boosting LiDAR-based Semantic Labeling by Cross-Modal Training Data Generation

no code implementations26 Apr 2018 Florian Piewak, Peter Pinggera, Manuel Schäfer, David Peter, Beate Schwarz, Nick Schneider, David Pfeiffer, Markus Enzweiler, Marius Zöllner

The effectiveness of the proposed network architecture as well as the automated data generation process is demonstrated on a manually annotated ground truth dataset.

The Stixel world: A medium-level representation of traffic scenes

no code implementations2 Apr 2017 Marius Cordts, Timo Rehfeld, Lukas Schneider, David Pfeiffer, Markus Enzweiler, Stefan Roth, Marc Pollefeys, Uwe Franke

We believe this challenge should be faced by introducing a representation of the sensory data that provides compressed and structured access to all relevant visual content of the scene.

Exploiting the Power of Stereo Confidences

no code implementations CVPR 2013 David Pfeiffer, Stefan Gehrig, Nicolai Schneider

Before using this information, a mapping from confidence values to disparity outlier probability rate is performed based on gathered disparity statistics from labeled video data.
