- Transportation terminals subject to capacity issues
- Need expressed by managers for analysis of passenger dynamics
- Bottleneck is high variety/complexity of passenger behaviours
|
- CCTV video streams never watched (e.g. in Turin, 28 monitors for 800 cameras).
- Monitors show empty scenes/spaces, while others cameras look at scenes in which something (even normal) is happening
- Probability to watch right streams at right time is very limited
|
- Human behaviour modelling not ready for real-scale environment
- Scene understanding based on location features not sufficiently reliable
- Need for robust human-centred features
|
- System able to identify and characterize structures inherent in collective behavior
- Continuous monitoring of user information
- locations, routes,
- spatio-temporal activities (walking, waiting...),
- interactions with others passengers and/or equipments,
- contextual data (time of day, density of people...)
- Goal: estimate trends of large-scale human behaviour at an infrastructure level, e.g. to
- Localize common loitering areas and/or highly frequented aisles,
- Identify traffic patterns in infrastructure,
- ...

- Mechanisms for selecting relevant audio/video streams in control rooms
- Models to characterise video streams content
- Trivial scenario when dealing with “empty vs occupied” scenes
- Challenging problem when almost all scenes are occupied
- Need for unsupervised modelling is even more explicit for audio streams (“mosaicing” of data is impossible due to transparent nature of sound)
- Goal: Development of autonomous content-based audio/video sensor selection system for control rooms
|
- Investigate 3 levels of human behaviours characterization in surveillance data
- Individual level
characterize an individual person with his/her activities
- Group level
detect small group of people and identify interactions in it
- Crowd level
monitor (dynamics of) crowd/flow of people
- Goal: Two applications
- Event detection applications for safety/security
- Environmental reporting for situational awareness
