Video Reconstruction using Diffusion-based Image-to-Video Generation with Trajectory Guidance
Stelio Bompai, Ioannis Kontopoulos, Giannis Spiliopoulos +2
This paper addresses the problem of reconstructing missing or dropped frames in top-down drone video of autonomous surface vehicles performing structured maritime manoeuvres. We pr…
Trajectory-Aware Adaptive Inference in Object Detection Models
Grigorios Papanikolaou, Ioannis Kontopoulos, Giannis Spiliopoulos +2
The increasing integration of sensors in autonomous maritime navigation has led to large-scale multimodal datasets, raising challenges in achieving efficient real-time perception.…
Context-Enriched Natural Language Descriptions of Vessel Trajectories
Kostas Patroumpas, Alexandros Troupiotis-Kapeliaris, Giannis Spiliopoulos +4
We address the problem of transforming raw vessel trajectory data collected from AIS into structured and semantically enriched representations interpretable by humans and directly…
Data-Driven Trajectory Imputation for Vessel Mobility Analysis
Giannis Spiliopoulos, Alexandros Troupiotis-Kapeliaris, Kostas Patroumpas +4
Modeling vessel activity at sea is critical for a wide range of applications, including route planning, transportation logistics, maritime safety, and environmental monitoring. Ove…
COVID-19 Impact on Global Maritime Mobility
Leonardo M. Millefiori, Paolo Braca, Dimitris Zissis +4
To prevent the outbreak of the Coronavirus disease (COVID-19), many countries around the world went into lockdown and imposed unprecedented containment measures. These restrictions…
