There are several discrete stages in the process.  Sensors view a scene and key features are extracted and grouped.  Objects are then identified, recognised and tracked both spatially and temporally.  Contexts and situations can be learnt and events triggered if specified parameters met.

The software is available in modules that address specific situations; counting, identifying gender, measuring density, observing queues, measuring attention time and tracking objects.  The underlying core software can be adapted to other situations if required.

Modules can be combined to further enhance reporting possibilities.

The use of visual image processing has a number of advantages over other technologies such as the use of lasers, infra-red sensors, thermal imaging or mechanical detectors:

• Video based systems are intuitive to set up and administer.

• They have the advantage of being suitable for any ceiling height – ideal for large public spaces and for outdoor situations.

• By using commercially available video capture equipment and processors, value is added in software. This allows an evolutionary development so that a system installed today can continue to be upgraded with new versions of software.

• Video based data collection is very adaptable; there is no requirement to modify a floor plan or customer flow in order to accommodate sensor limitations.
