TL;DR
This paper introduces a relaxed co-movement pattern definition and a novel MaxGrowth enumeration framework to efficiently identify vehicle groups traveling together in urban traffic videos, even with imperfect trajectory data.
Contribution
It proposes a new relaxed pattern definition and a verification-free enumeration framework, significantly improving efficiency and robustness over previous methods.
Findings
MaxGrowth is up to 100 times faster than baseline algorithms.
The approach maintains high accuracy despite imperfect trajectory data.
Extensive experiments validate the efficiency and effectiveness of the proposed methods.
Abstract
Discovering co-movement patterns from urban-scale video data sources has emerged as an attractive topic. This task aims to identify groups of objects that travel together along a common route, which offers effective support for government agencies in enhancing smart city management. However, the previous work has made a strong assumption on the accuracy of recovered trajectories from videos and their co-movement pattern definition requires the group of objects to appear across consecutive cameras along the common route. In practice, this often leads to missing patterns if a vehicle is not correctly identified from a certain camera due to object occlusion or vehicle mis-matching. To address this challenge, we propose a relaxed definition of co-movement patterns from video data, which removes the consecutiveness requirement in the common route and accommodates a certain number of missing…
