Posterity Logging of Face Imagery for Video Surveillance
Found in: IEEE MultiMedia
By Andrew D. Bagdanov,Alberto Del Bimbo,Fabrizio Dini,Giuseppe Lisanti,Iacopo Masi
Issue Date:October 2012
pp. 48-59
A real-time posterity logging system detects and tracks multiple targets in video streams, grabbing face images and retaining only the best quality for each detected target.
 
Sensor Fusion for Cooperative Head Localization
Found in: Pattern Recognition, International Conference on
By Alberto Del Bimbo, Fabrizio Dini, Giuseppe Lisanti, Federico Pernici
Issue Date:August 2010
pp. 384-387
In modern video surveillance systems, pan–tilt– zoom (PTZ) cameras certainly have the potential to allow the coverage of wide areas with a much smaller number of sensors, compared to the common approach of fixed camera networks. This paper describes a gene...
 
Adaptive uncertainty estimation for particle filter-based trackers
Found in: Image Analysis and Processing, International Conference on
By Andrew D. Bagdanov, Alberto Del Bimbo, Fabrizio Dini, Walter Nunziati
Issue Date:September 2007
pp. 331-336
In particle filter.based visual trackers, dynamic velocity components are typically incorporated into the state update equations. In these cases, there is a risk that the uncertainty in the model update stage can become amplified in unexpected and undesira...
