Virginia Fernandez Arguedas (QMUL) visiting ISDEFE
16.04.2012 - 30.04.2012
Internal Visits


The intention of this placement was to promote the integration of Queen Mary University and ISDEFE by understanding the different approaches used for collaboration in privacy issues of video surveillance within the public sector in order to find common ground. During the visit, QMUL exchanged the knowledge with ISDEFE in video surveillance systems and footage handling in object detection, classification and privacy mechanism related to behaviour. The ISDEFE position in the public sector to gather requirements for video surveillance systems in urban scenarios to foster future developments based on research has been taken in advance for further understanding of existing issues.
The different approaches proposed by ISDEFE and QMUL make it possible to bridge the gap between the privacy issues, user needs and the technical requirements for video surveillance systems. Consequently, during the two weeks industrial placement ISDEFE and QMUL have worked together to combine their two complementary approaches.
During the industrial placement, the final user needs were analysed for the definition of a set of usecases, such as “crash and carry” and traffic accidents event detection. A compendium of the different use-cases was proposed for the development of a forensic search tool, which enables the efficient semantic labelling, storage and retrieval of relevant information by exploiting the behavioural information implicit within the moving objects.
Due to the mandatory compliance of the surveillance video analysis techniques with privacy protection and ethical laws, an in-depth analysis of the privacy, ethical and user constraints and requirements for the abovementioned forensic search tool was carried out.
The main requirement i for industry is a need for more cameras tto be incorporated into the video surveillance system in an urban scenario. Also, the need for improvements on video analysis based on existing camera features, interoperability and environment adaptability are envisaged on prevention, investigation and a chain of custody issues.
The future plan for collaboration between ISDEFE and QMUL will focus on the development of the proposed forensic search tool considering not only the final user requirements but also its compliance with the privacy and ethical constraints.
Such a forensic search tool is composed of a set of predefined scenarios and use-cases, for the detection of events of special interest for the final user, such as “crash and carry”. , an extension of the use-cases is planned as future work for the enlargement of the surveillance ontology. As an extension of the collaborative work a publication in IEEE-IFS is planned. This research exchange had contributed to number of VideoSense activities, mainly in WP2, WP5, WP6 and WP7.
