摘要

Unreasonable trajectory segmentation will lead to inaccurate results about pedestrian anomaly detection. To solve this problem, this paper proposed a multi-feature and multiresolution feature representation method combining global and local features of the trajectory. First, the trajectories are grouped using the DBSCAN clustering algorithm according to the direction of movement. Generate a Fittin...
