Map matching queries on realistic input graphs under the Fréchet distance
Joachim Gudmundsson, Martin P. Seybold, Sampson Wong
Map matching is a common preprocessing step for analysing vehicle trajectories. In the theory community, the most popular approach for map matching is to compute a path on the road…
On Practical Nearest Sub-Trajectory Queries under the Fréchet Distance
Joachim Gudmundsson, John Pfeifer, Martin P. Seybold
We study the problem of sub-trajectory nearest-neighbor queries on polygonal curves under the continuous Fréchet distance. Given an vertex trajectory and an vertex quer…
Exploring Sub-skeleton Trajectories for Interpretable Recognition of Sign Language
Joachim Gudmundsson, Martin P. Seybold, John Pfeifer
Recent advances in tracking sensors and pose estimation software enable smart systems to use trajectories of skeleton joint locations for supervised learning. We study the problem…
