Human Motion Trajectory Prediction: A Survey

no code implementations15 May 2019 Andrey Rudenko, Luigi Palmieri, Michael Herman, Kris M. Kitani, Dariu M. Gavrila, Kai O. Arras

With growing numbers of intelligent autonomous systems in human environments, the ability of such systems to perceive, understand and anticipate human behavior becomes increasingly important.

CNN based Road User Detection using the 3D Radar Cube

1 code implementation25 Apr 2020 Andras Palffy, Jiaao Dong, Julian F. P. Kooij, Dariu M. Gavrila

In experiments on a real-life dataset we demonstrate that our method outperforms the state-of-the-art methods both target- and object-wise by reaching an average of 0. 70 (baseline: 0. 68) target-wise and 0. 56 (baseline: 0. 48) object-wise F1 score.

Semantic Scene Completion using Local Deep Implicit Functions on LiDAR Data

no code implementations18 Nov 2020 Christoph B. Rist, David Emmerichs, Markus Enzweiler, Dariu M. Gavrila

We show that this continuous representation is suitable to encode geometric and semantic properties of extensive outdoor scenes without the need for spatial discretization (thus avoiding the trade-off between level of scene detail and the scene extent that can be covered).

Structural Knowledge Distillation for Object Detection

no code implementations23 Nov 2022 Philip de Rijk, Lukas Schneider, Marius Cordts, Dariu M. Gavrila

Knowledge Distillation (KD) is a well-known training paradigm in deep neural networks where knowledge acquired by a large teacher model is transferred to a small student.

How do Cross-View and Cross-Modal Alignment Affect Representations in Contrastive Learning?

no code implementations23 Nov 2022 Thomas M. Hehn, Julian F. P. Kooij, Dariu M. Gavrila

Various state-of-the-art self-supervised visual representation learning approaches take advantage of data from multiple sensors by aligning the feature representations across views and/or modalities.

Multimodal Object Query Initialization for 3D Object Detection

no code implementations16 Oct 2023 Mathijs R. van Geerenstein, Felicia Ruppel, Klaus Dietmayer, Dariu M. Gavrila

In experiments, we outperform the state of the art in transformer-based LiDAR object detection on the competitive nuScenes benchmark and showcase the benefits of input-dependent multimodal query initialization, while being more efficient than the available alternatives for LiDAR-camera initialization.

See Further Than CFAR: a Data-Driven Radar Detector Trained by Lidar

no code implementations20 Feb 2024 Ignacio Roldan, Andras Palffy, Julian F. P. Kooij, Dariu M. Gavrila, Francesco Fioranelli, Alexander Yarovoy

In this paper, we address the limitations of traditional constant false alarm rate (CFAR) target detectors in automotive radars, particularly in complex urban environments with multiple objects that appear as extended targets.
