Distribution-Based Trajectory Clustering [PDF]

open access: yes2023 IEEE International Conference on Data Mining (ICDM), 2023
Trajectory clustering enables the discovery of common patterns in trajectory data. Current methods of trajectory clustering rely on a distance measure between two points in order to measure the dissimilarity between two trajectories. The distance measures employed have two challenges: high computational cost and low fidelity.

Air Traffic Trajectory Operation Mode Mining Based on Clustering

open access: yesApplied Sciences, 2022
When processing track sequences, it is time-consuming and difficult to separate clusters with substantial density variations to deal with the problem of classic clustering methods mining common flight patterns in airspace.

Trajectory clustering for coastal surveillance

open access: yes2007 10th International Conference on Information Fusion, 2007
Achieving superior situation awareness is a key task for military, as well as civilian, decision makers. Today, automatic systems provide us with an excellent opportunity for assisting the human decision maker in achieving this awareness. Due to the potential of information overload one important aspect is to understand where to focus attention ...

Learned Trajectory Embedding for Subspace Clustering

open access: yes2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
Clustering multiple motions from observed point trajectories is a fundamental task in understanding dynamic scenes. Most motion models require multiple tracks to estimate their parameters, hence identifying clusters when multiple motions are observed is ...
