DNN-Based Map Deviation Detection in LiDAR Point Clouds

1 code implementation Open Journal on ITS 2023 Christopher Plachetka, Benjamin Sertolli, Jenny Fricke, Marvin Klingner, Tim Fingscheidt

In this work we present a novel deep learning-based approach to detect and specify map deviations in erroneous or outdated high-definition (HD) maps using both sensor and map data as input to a deep neural network (DNN).

X-Align++: cross-modal cross-view alignment for Bird's-eye-view segmentation

no code implementations6 Jun 2023 Shubhankar Borse, Senthil Yogamani, Marvin Klingner, Varun Ravi, Hong Cai, Abdulaziz Almuzairee, Fatih Porikli

Bird's-eye-view (BEV) grid is a typical representation of the perception of road components, e. g., drivable area, in autonomous driving.

X$^3$KD: Knowledge Distillation Across Modalities, Tasks and Stages for Multi-Camera 3D Object Detection

no code implementations3 Mar 2023 Marvin Klingner, Shubhankar Borse, Varun Ravi Kumar, Behnaz Rezaei, Venkatraman Narayanan, Senthil Yogamani, Fatih Porikli

Specifically, we propose cross-task distillation from an instance segmentation teacher (X-IS) in the PV feature extraction stage providing supervision without ambiguous error backpropagation through the view transformation.

The emergence of data-driven machine learning (ML) has facilitated significant progress in many complicated tasks such as highly-automated driving.

Detecting Adversarial Perturbations in Multi-Task Perception

1 code implementation2 Mar 2022 Marvin Klingner, Varun Ravi Kumar, Senthil Yogamani, Andreas Bär, Tim Fingscheidt

In this paper, we (i) propose a novel adversarial perturbation detection scheme based on multi-task perception of complex vision tasks (i. e., depth estimation and semantic segmentation).

Self-Supervised Monocular Depth Estimation: Solving the Dynamic Object Problem by Semantic Guidance

1 code implementation ECCV 2020 Marvin Klingner, Jan-Aike Termöhlen, Jonas Mikolajczyk, Tim Fingscheidt

Self-supervised monocular depth estimation presents a powerful method to obtain 3D scene information from single camera images, which is trainable on arbitrary image sequences without requiring depth labels, e. g., from a LiDAR sensor.

Class-Incremental Learning for Semantic Segmentation Re-Using Neither Old Data Nor Old Labels

1 code implementation12 May 2020 Marvin Klingner, Andreas Bär, Philipp Donn, Tim Fingscheidt

While neural networks trained for semantic segmentation are essential for perception in autonomous driving, most current algorithms assume a fixed number of classes, presenting a major limitation when developing new autonomous driving systems with the need of additional classes.

Improved Noise and Attack Robustness for Semantic Segmentation by Using Multi-Task Training with Self-Supervised Depth Estimation

no code implementations23 Apr 2020 Marvin Klingner, Andreas Bär, Tim Fingscheidt

We show the effectiveness of our method on the Cityscapes dataset, where our multi-task training approach consistently outperforms the single-task semantic segmentation baseline in terms of both robustness vs. noise and in terms of adversarial attacks, without the need for depth labels in training.
