The challenge
• To use persistent visual surveillance data to maintain and improve the security and efficiency of our urban centres in the face of rapid growth and increasing complexity
3
Current obstacles
• Most surveillance data are ignored due to lack of adequate manpower and reliable visual algorithms.
• Persistent visual surveillance systems are poorly integrated with other forms of geospatial information
• Surveillance cams compress the 3D scene into 2D, making inference difficult
4
Example (real, but anonymous public institution)
400 cameras 8 monitors 2 vigilant undergraduates
What if something happens?

Goals
• Automatic, efficient, scaleable methods for extraction and integration of 2D and 3D urban data at street level– Surveillance video, UAV photogrammetry, airborne & terrestrial
LIDAR…
• Automatic inference of 3D scene properties– Scene segmentation, building characteristics, foliage modeling
• Automatic inference of 3D scene dynamics– Human and pedestrian traffic
• Integrated reporting and 3D visualization– For efficient human interpretation
• Integration into distributed software architecture– CAE S-Mission architecture
10
Scientific Questions
• There are many, e.g.,– How can 3D urban scene information be reliably extracted from
single-view video?
– How can individuals be discriminated in crowds?
– How can free-form structures (e.g., trees) be reliably segmented from the scene?
– How can multiple forms of geolocation data (GPS, inertial, visual) be integrated to optimize positioning?
