Trajectory multi-Bernoulli filters for multi-target tracking based on sets of trajectories
2020 IEEE 23rd International Conference on Information Fusion (FUSION), 2020This paper presents two multi-Bernoulli filters on sets of trajectories for multiple target tracking. The first filter provides a multi-Bernoulli approximation of the posterior density over the set of alive trajectories at the current time step. The second filter provides a multi-Bernoulli approximation of the posterior density over the set of all ...

Contextual grammars with uniform sets of trajectories
Fundam. Informaticae, 2005Summary: A uniformcontextual grammar with contexts shuffled along trajectories uses the same set of trajectories for each context. We prove that when the alphabet has at least two symbols, the nonuniform contextual grammars with trajectories are strictly more powerful than the uniform variant.

Efficient one-click browsing of large trajectory sets
Proceedings of the 22nd ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2014Traffic researchers, planners, and analysts want a simple way to query the large quantities of GPS trajectories collected from vehicles. In addition, users expect the results to be presented immediately even when querying very large transportation networks with huge trajectory data sets.

Trajectory Set Similarity Measure: An EMD-Based Approach
2018To address the trajectory sparsity issue concerning Origin-Destination (OD) pairs, in general, most existing studies strive to reconstruct trajectories by concatenating the sub-trajectories along the specific paths and filling up the sparsity with conceptual trajectories.

The fireworks effect: exploring trajectory sets in time
Computing in Science & Engineering, 2002Many students in physics and engineering courses often grapple with the mathematics they encounter and struggle to extract meaning from the analytic material they are learning, Much can be done computationally at this level to ask questions about and explore analytic functions or results in a numeric environment.

Proceedings of the 16th International Symposium on Spatial and Temporal Databases, 2019
We consider the problem of indexing massive trajectory data in an underlying road network. Our Pathfinder index structure is based on a state-of-the-art speed-up technique for shortest path planning and allows to both compress and access huge amounts of trajectory data.
