Face recognition, demonstrated at the bench
A live evaluation session: a network camera on a tripod, the engine running on a laptop, and a printed reference portrait used as the probe image.
Partner evaluations start the same way a customer deployment does — with a camera pointed at a real room and a question about whether the result is good enough to build on. The camera on the tripod feeds the engine on the laptop; the printed portrait is the reference the engine is asked to match against.
Running it in the room rather than showing a recording is deliberate. It is the only way a partner's technical lead can change the angle, the distance and the lighting and see what happens — which is exactly what they will have to answer for on site.
