Face Detection jQuery Plugin

While the plugin is probably awesome, there are two things that really suck here.

1. Lack of a real demo. This is the sort of thing that will not convince me until I can click "upload" and have a detected face on my own crappy image.

2. There is no clear link to the actual plugin. I know we're all web guys and can extract links from source, but come on. Even the "source on github" text isn't a link ...

edit: the word Github is a link, but there is no visual way of distinguishing it from the rest of the text, which leaves me dazed and confused.

I tried to replace the image, but not being a jquery wizard, I may've done something wrong. In the end, it said there was an issue with the image. Using the jquery selectors plugin, I ran (with the first SFW image I could find):

$(img).attr("src", "http://www.accesshollywood.com/content/images/82/300x300/821...)

I think you'll find it won't work with images loaded from other domains.

There is a cross-domain data protection feature on Canvas.

"the word Github is a link, but there is no visual way of distinguishing it from the rest of the text"

The links are purple instead of black. It's not much of a contrast though.

This uses the face detection library here: http://badassjs.com/post/1461943420/face-detection-in-javasc...

Which has a link to upload and test your own pictures here: http://liuliu.me/detect/detect.html

Detection is the easy part -- recognition has always been the stumper!

Detection is pretty useful though.

Combine this with something like http://nicklothian.com/blog/2009/12/15/using-flash-to-shim-a... and you might be able to do facetracking in Javascript

I actually worked on a face-tracker using Python and a webcam mounted on servos as a research project on a quad-core. I highly doubt the Python added much overhead (we were using OpenCV, which is compiled), and it still wasn't very elegant; however, you make an excellent point. Once we can push web technologies to make JavaScript capable of computer vision, or use other technologies/plugins that empower computer-vision in-browser, simple applications like video surveillance will get much more interesting.

EDIT: Just a thought, wouldn't it be cool if we didn't have to ring doorbells anymore? There'd be a webcam instead of a lens on the door, and a small computer that notifies you when someone's at your door. It could even tell you who they are if we create adequate recognition technologies.

Actually, I've worked on a hand gesture recognition thing on web for quite some time (http://api.alii.tv/). The unfortunate part is, that is a plugin, and it is really hard to make a plugin compatible with every machine in wild.

That's exactly why I wrote my flash shim thing.

(Although, for real usage you'd actually have to do it in Flash still because of a Webkit memory leak)

... sure, if you consider the mouth as not really part of the face :-/

He's not using that money to buy beer..

where is the download link?

where it says "source on github"...

This is awesome.
