Imagery Library for Intelligent Detection Systems (i-LIDS); A Standard for Testing Video Based Detection Systems

The Home Office Scientific Development Branch (HOSDB) evaluates intelligent CCTV and video-based detection systems (VBDS) for security and policing purposes. The commercial market for VBDS is diverse and continues to grow rapidly, yet there are no current standards to assess the performance of these systems. Many government users would like to use VBDS for outdoor applications. However, the systems tend to struggle with changing environmental conditions such as moving shadows and lighting changes. In order to be able to rapidly and reliably assess the performance of VBDS, HOSDB in partnership with the security service has produced a video test library, i-LIDS (imagery library for intelligent detection systems), a sample of which was released on DVD in 2005. The principal aim of i-LIDS is to provide a collection of CCTV images that can be used to provide typical real-world footage for research groups to use in their development programmes; and to evaluate the performance of video-based detection systems (VBDS) against government requirements
