Make a networked face sensor with Processing
This Codebox explores how to use a web server to collect sensor data from a Processing sketch. As an example, we’ll use OpenCV to periodically detect and report number of faces that appear in your webcam’s field of view. You might use something like this at a conference or art show to see how many people are interested in a particular session or exhibit. Using this data feed, you might then create a mobile app that would show you where the most people are at a conference at any given time.
