TraClass: Trajectory Classification Using Hierarchical Region-Based and Trajectory-Based Clustering
Summary: TraClass proposes hierarchical feature generation for trajectories, partitioning paths to reveal parts. Regional clustering yields region features; trajectory clustering yields movement features; together, multi-level features improve classification. (summarized by gpt-5-nano on Feb 09 2026)
