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.
Continuous recovery for real time pan tilt zoom localization and mapping
Found in: Advanced Video and Signal Based Surveillance, IEEE Conference on
By Alberto Del Bimbo,Giuseppe Lisanti,Iacopo Masi,Federico Pernici
Issue Date:September 2011
pp. 160-165
We propose a method for real time recovering from tracking failure in monocular localization and mapping with a Pan Tilt Zoom camera (PTZ). The method automatically detects and seamlessly recovers from tracking failure while preserving map integrity. By ex...
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...
Person Detection Using Temporal and Geometric Context with a Pan Tilt Zoom Camera
Found in: Pattern Recognition, International Conference on
By Alberto Del Bimbo, Giuseppe Lisanti, Iacopo Masi, Federico Pernici
Issue Date:August 2010
pp. 3886-3889
In this paper we present a system that integrates automatic camera geometry estimation and object detection from a Pan Tilt Zoom camera. We estimate camera pose with respect to a world scene plane in real-time and perform human detection exploiting the rel...
Information theoretic sensor management for multi-target tracking with a single pan-tilt-zoom camera
Found in: 2014 IEEE Winter Conference on Applications of Computer Vision (WACV)
By Pietro Salvagnini,Federico Pernici,Marco Cristani,Giuseppe Lisanti,Iacopo Masi,Alberto Del Bimbo,Vittorio Murino
Issue Date:March 2014
pp. 893-900
Automatic multiple target tracking with pan-tilt-zoom (PTZ) cameras is a hard task, with few approaches in the literature, most of them proposing simplistic scenarios. In this paper, we present a PTZ camera management framework which lies on information th...
