Ding, Fangqiang (author), Palffy, A. (author), Gavrila, D. (author), Lu, Chris Xiaoxuan (author)This work proposes a novel approach to 4D radar-based scene flow estimation via cross-modal learning. Our approach is motivated by the co-located sensing redundancy in modern autonomous vehicles. Such redundancy implicitly provides various forms of supervision cues to the radar scene flow estimation. Specifically, we introduce a multi-task model...conference paper 2023

Palffy, A. (author), Kooij, J.F.P. (author), Gavrila, D. (author)Early and accurate detection of crossing pedestrians is crucial in automated driving in order to perform timely emergency manoeuvres. However, this is a difficult task in urban scenarios where pedestrians are often occluded (not visible) behind objects, e.g., other parked vehicles. We propose an occlusion aware fusion of stereo camera and...journal article 2023

Palffy, A. (author)This thesis addresses the problem of object detection with automotive radar sensors in the field of intelligent vehicles with special attention to vulnerable road users: pedestrians, cyclists, and motorcyclists. It is not the goal of this work to improve the hardware design or signal processing algorithms of the radar sensors themselves, but to...doctoral thesis 2022

Palffy, A. (author), Pool, E.A.I. (author), Baratam, Srimannarayana (author), Kooij, J.F.P. (author), Gavrila, D. (author)Next-generation automotive radars provide elevation data in addition to range-, azimuth- and Doppler velocity. In this experimental study, we apply a state-of-the-art object detector (PointPillars), previously used for LiDAR 3D data, to such 3+1D radar data (where 1D refers to Doppler). In ablation studies, we first explore the benefits of...journal article 2022

Palffy, A. (author), Dong, Jiaao (author), Kooij, J.F.P. (author), Gavrila, D. (author)This letter presents a novel radar based, single-frame, multi-class detection method for moving road users ( pedestrian, cyclist, car ), which utilizes low-level radar cube data. The method provides class information both on the radar target- and object-level. Radar targets are classified individually after extending the target features with a...journal article 2020
