This post will demonstrate the feasability of face detection in web cam feeds grabbed by a flash/flex application. It’s inspired by a prototype of Martin Speelmans, informed by my work with Flash and web cams and my experiments with OpenCV. The basic premise is that a flex application running in a users browser grabs web cam shots, compresses them and sends them to a server. The server decompresses the picture, does face detection on it, and sends the result back to the client. All fast enough to give the user a relatively smooth experience. A fairly impressive Actionscript 3 face detection implementation exists, but my guess is that — barring a quantum leap in Adobe compiler technology — it’s gonna be a few years before fast, reliable Actionscript 3 face detection is feasible in Flash Player. Silverlight may be a different story, but it doesn’t support web cams yet.
