I was thinking that cameras should have this feature - they can detect humans smiling at the camera, but what we really need is a camera that can take a photo of a cat _while_ its looking in the right direction dammit

I prefer one that takes a picture of a cat and knows when it is bringing something home. See http://hackaday.com/2010/05/14/cat-door-unlocks-via-facial-r... for more.

This could be huge in Japan!

Rendering KittenAuth obsolete

I love it. Hopefully I'll be able to integrate it as chrome extension so I can block all cats on reddit and other sites.

Or use it to block everything but cats, greatly improving your internet experience.

We made a fun website using this library – http://mycatandi.com

To paraphrase Nathan Hale, I regret I have but only one up-vote to give.

Brilliant.

A js anti cat photo-bombing library! My cat likes to get into every pic we take around the living room (not sure why). I hope this and other technologies could help serve as a strategic deterrent against him - we're on to you :)

It did not detect any cats in this picture:

That's because they're kittens, not cats. Duh.

I wonder how well this would defeat microsoft asirra http://research.microsoft.com/asirra

Thankyou!!!

I'm going to test this on my 2 lovely kittens (almost a year old now, so not really kittens anymore) and see how it goes.

It would be nice if Google (and maybe Facebook) enabled something like this by default, considering the meme-level quantity of kitty photos they must deal with. I'd love it if Google+ tagged my kitties automatically :-)

I'm pretty sure the Intercat overlords are not going to be pleased. I was thinking about going to TXJS this weekend but think I'll stay home and build my feline shrine to Intercats instead.

Now that the Intercats know what is possible, that's probably a good idea.

May I suggest a sacrificial ball-of-string alter? Or possibly a cardboard box with a laser-pointer-disco-ball inside (This may be impossible, but try for Intercat's Glory). Cardboard boxes seem to be an integral part of the feline spirituality.

Oooh, I really love that cardboard box idea, not only as a shrine, but as a weekend project for my own Intercats. It may in fact be impossible but I think with the Intercat as my spiritual guide, I've got a good chance.

If you achieve said shrine, can you post photos?

This could be really useful if it could be integrated with some hardware to make cat doors that open only for your cat... or at least a cat...

Wasn't this also on HN a few months ago? Or a year perhaps. I definitely remember some sort of cat face detection in Javascript.

It came up in relation to https://news.ycombinator.com/item?id=5106767 (though not in this particular thread)

Yes: https://news.ycombinator.com/item?id=4584453.

Looks like it has improved since then. Nifty :-)

Hummm fail? http://screencast.com/t/kxFQ3sBkmCo

http://meow.vc approves. we want to talk to you.

Okay, stupid question, what would it take to re-code this for human face detection?

This makes it to the front page once every few months

Really, that's surprising, I thought once it made it once it would be bookmarked by every HN cat owner out there. Must have missed it the last few times!
