Addressing challenges in utilizing visual surveillance data for urban security and efficiency, integrating 2D and 3D data for better monitoring and decision-making, diverse applications in public and private security, urban planning, and business analytics.

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
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
8 monitors 2 vigilant undergraduates 400 cameras Example (real, but anonymous public institution) 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 3Dscene dynamics • Human and pedestrian traffic • Integrated reporting and 3D visualization • For efficient human interpretation • Integration into distributed software architecture • CAE S-Mission architecture
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?
Applications • Public and private security • Urban planning • Business analytics
