Just using javascript from two years ago: http://facedetection.jaysalvat.com/ (hn comments: http://news.ycombinator.com/item?id=2002316)

Seems to me you could have just had Jetty/OpenCV send back the coords of the faces, then have Javascript draw a box around them. Would have saved quite a bit of bandwidth and removed the need for experimental APIs.

I think you would still want WebRTC and Web Sockets to stream the webcam to Jetty/OpenCV. Yeah, he could have sent just coords back to save on bandwidth though.

Try this version too: http://neave.com/webcam/html5/face/

It doesn't require WebSockets or Jetty. Just good ol' JavaScript/HTML5. Nothing more.

Where's the demo link? I couldn't find one, but I'm assuming nobody would write an HTML5 tutorial without a link to a demo page...

s/HTML5/HTML-ng/

Just because HTML5 != work in every HTML5 browser. "Numbers don't mean anything anymore they say". Well for HTML5 thats pretty much spot on.. and that's unfortunate.

The demo's cool tho :)

Are you quoting something? Google just returns this thread when I search that.

Err.. Chrome, Firefox version numbers and the need for "rapid releases" and "always-on-going-HTML5 <standard>".

(Pretty sure the dictionary has a different interpretation of "standard"). Google != your brain.

I was talking about the part you put in quotes:

  "Numbers don't mean anything anymore they say"

Normally quote marks (the " character) are used if you're quoting something, so I was wondering where you are quoting that from. To be pedantic, what I'm looking for is a citation (of the quote, not of the fact).

It isn't loading for me.
