Abstract: The system offers a comprehensive mechanism for tracking several individuals and measuring their combined actions. Our method assumes that a person's mobility, activity, and neighbouring people's motions and behaviours are meaningfully interconnected. We propose a hierarchy of activity types to allow a more natural transition from solo mobility to communal motion. The approach provides a two-tiered hierarchical graphical model to learn the spatial and temporal links between tracks, tracks, and activity segments. We also propose combining conviction engendering with a branch and bound methodology modified with whole number programming to solve this intractable joint inference problem. This work uses motion and context data to jointly model and detect associated movie actions. The realisation that geographically and temporally related events rarely happen separately and often serve as backdrops prompted this. A hierarchical two-layer conditional random field model represents action segments and activities. The model integrates motion and backdrop variables at numerous levels and generates statistics that automatically identify typical patterns.
