The Imagery Library for Intelligent Detection Systems (iLids) is the UK Government's standard for Video
Based Detection Systems (VBDS). The first four iLids scenarios were released in November 2006 and
annual evaluations for these four scenarios began in 2007.
The Home Office Scientific Development Branch (HOSDB), in partnership with the Centre for the
Protection of National Infrastructure (CPNI), has also developed a fifth iLids Scenario; Multiple Camera
Tracking (MCT). The fifth scenario data sets were made available in November 2008 to industry, academic
and commercial research organizations The imagery contains various staged events of people walking
through the camera views. Multiple Camera Tracking Systems (MCTS) are expected to initialise on a
specific target and be able to track the target over some or all of the camera views.
HOSDB and CPNI are now working on a sixth iLids dataset series. These datasets will cover several
technology areas:
• Thermal imaging systems
• Systems that rely on active IR illumination
The aim is to develop libraries that promote the development of systems that are able to demonstrate
effective performance in the key application area of people and vehicular detection at a distance.
This paper will:
• Describe the evaluation process, infrastructure and tools that HOSDB will use to evaluate MCT
systems. Building on the success of our previous automated tools for evaluation, HOSDB has
developed the MCT evaluation tool CLAYMORE. CLAYMORE is a tool for the real-time
evaluation of MCT systems.
• Provide an overview of the new sixth scenario aims and objectives, library specifications and
timescales for release.
The Imagery Library for Intelligent Detection Systems (i-LIDS) is the UK government's standard for Video Based Detection Systems (VBDS).
The Home Office Scientific Development Branch (HOSDB) in partnership with the Centre for the Protection of National Infrastructure (CPNI) has now developed a fifth i-LIDS Scenario; Multiple Camera Tracking (MCT).
The imagery contains various staged events of people walking through the camera views. A bounding box Ground Truth is provided with the imagery.
A metric has been developed by HOSDB for evaluation of systems. The metric is based on precision and recall system output compared to the ground truth.
