I'm interested in commissioning a project for someone to build a system to count the number of people who look into a camera over a set period of time, whether through use of multiple shots / images per second or live video. It needs to also be capable of recognising a face so that it doesn't count them twice if they stay in front of the camera for a longer period too. Any demographic male / female or age range information that can be gained is beneficial but secondary. I can send images of the initial dashboard designs (to be built by us - fed by data supplied by your system) once we have agreed to commence the project. I believe that OpenCV is the library / framework we wish to use but am open to Matlab or others.
