Network-centric smart video surveillance has witnessed a surge of interest from both diverse business sectors and research communities over the last decade. BT's recent transformation from a dominant fixed line Telco in the UK to a leading networked ICT service provider worldwide has spurred our researches in this and allied field so as to provide value-added services and solutions, addressing the...
More and more cameras are being installed everyday for safety, security and intelligence gathering purposes, making the volume of storage videos increase all the time. It is therefore important to manage this resource to be able to cast a structured (hierarchical) view into the activities of long video files to catalogue only interesting or relevant domain events. This paper aims to address this issue...
The paper investigates a novel and effective approach for real-time analysis of crowd congestion (density) in a physical space monitored by surveillance cameras. A region of interest (ROI) is specified in the space and partition of the ROI into an irregular array of sub-regions (blobs) automatically carried out, to each of which a congestion contributor is computed. The method then exploits the short-term...
