 Obiettivo del progetto (Objective)

'The SAVASA project proposes the creation of a video archive search platform that allows authorised users to perform semantic queries over different, remote and non-interoperable video archives this project will exploit the current trends in computer vision, video retrieval and semantic video analysis. It is also a goal of the project to ensure that its results are capable of deployment in distributed systems and as software services. However, technology for technologies sake is of little value. Therefore the involvement of ethicist, legal experts and, most importantly, those users who must operate Video Archive installations and services to meet the needs of law enforcement agencies and judicial authorities, as well as those of civil protection and day-to-day organisational needs, is required. The SAVASA consortium covers each of these roles. At its core, SAVASA will use existing reference technologies from the ICT field that have overcome the barrier of system interoperability/compatibility, i.e. between container and compression formats. The project will implement a prototype platform capable of demonstrating unified archive integration and an approach to common search and indexing. The project will also provide a set of tailored video analytics and semantic analysis tools that will provide added value to end-users, but which can also function within a legal and ethical framework. The project will provide an analysis of existing technical barriers/requirements in the standardisation of technologies and procedures, via the validation testing of a prototype platform with end users. Finally, SAVASA will implement a project structure that will ensure that RTD, Legal, Ethical and End User needs are properly balanced and addressed.'

Introduzione (Teaser)

An EU initiative has developed a new cloud-based platform to search videos from closed-circuit television (CCTV) archives. This platform helps law enforcement in their crime investigations and reinforces Europe's security.

Descrizione progetto (Article)

Today, there are a variety of video and storage formats that are used in existing CCTV systems. This means that each system must be accessed externally in a specific way, which complicates post-investigation tasks carried out by law enforcement agencies. Authorities require a way to make the CCTV systems interoperable. Achieving this goal was the aim of the EU-funded http://www.savasa.eu/ (SAVASA) (Standards based approach to video archive search and analysis) project.

The project set out to create a new search platform. Through the use of cloud computing technologies, SAVASA helped provide a solution for interoperability and enabled end users to access remote video archives.

Work began with the identification of user needs. End-user requirements were then translated into specifications for the new platform. The team developed a set of tailored video analytics and semantic analysis tools.

SAVASA addressed the legal and operational aspects of operating video surveillance systems by examining relevant European and national legislation that applies to the areas where end users are based and validation was performed. Ethical experts were brought in to ensure that outcomes are permitted from a legal, operational and ethical perspective.

Validation of the prototype platform enabled project partners to analyse current technical barriers and requirements in the standardisation of technologies and procedures. They also established protocols and guidelines to ensure that the technological aspects of SAVASA continue to develop according to their required recommendations.

SAVASA was able to fully exploit the potential of video surveillance systems by overcoming several major existing barriers. Better crime detection tools should reduce or prevent criminal activities, leading to enhanced security across the EU.
