Cat door unlocks via facial recognition

Faced with critters trying to get in and a cat that loved to show them her latest kill, the folks at Quantum Picture came up with a system that unlocks the cat door based on image recognition. As you can see above, it uses a camera to capture the profile of anything approaching the cat door. That image is compared to stored positive identification sets, making up a feline positive identification protocol. Don’t think this is necessary? In the writeup there’s a couple of images showing the outline of a skunk. Sounds like this system is a necessity.

We wonder if this lucky cat also has an Internet enabled cat feeder?

    This is AWESOME!

    Keeps out the skunks and squirrels!

    I remember reading this web page 10 years ago. Quite and old project, but one of my favorites to this day.

    You should actually be proud of his new non-breathing friends; When a cat brings you a dead animal they just kill, they’re showing you appreciation and admitting you’re the alpha male. I hate it when I see dead lizards and when I saw my neighbor’s dead goose, but let him know I’m “grateful”…

    while being excessively cool, this is as old as the internet :)

    I would combine ist with a rfid reader which only opens for my chipped kitteh..

  5. NatureTM says:

    I like it, but somemone send these guys an rfid kit pls.

  6. Emanuel says:

    I personally think this is overkill. Simpler would be make an RFID reader on the door and it would open the door when it detects the tag on the cats Collar. That way it works 100% of the time and you don’t have your cat stuck outside because of a bad facial angle or something.

  7. HawkeyeGuru says:

    RFID can’t do what this set up does. Facial recognition won’t allow kitty in if she is carrying an dead mouse or lizzard.

    I would add a clock to it so that she can’t get out at night when the cyotes are about.

  8. kwijibo says:

    the point was to stop the cat bringing animals inside, RFID wouldn’t prevent that at all

  9. lostalaska says:

    RFID won’t detect if the cat has a dead rodent in it’s mouth as it comes back in the house. Which seemed to be part of the criteria they used when building this contraption. Still RFID does seem like a cheaper solution than a side profile camera setup.

    Still I don’t think this setup would prevent laser cats from entering your house… nothing can stop laser cats.

  10. kvmanii says:

    wouldnt this let stray cats in with similar profiles

  11. Min says:

    No prawns allowed huh?

  12. blue carbuncle says:

    Super cool! Just what the wife and I need. We also need a non black cat lol. It is so hard to take “regular” pics of her. Again, builder, awesome job :)

  13. hpux735 says:

    Just as an FYI, I don’t think RFID was even available when this project first came out. Also, it’s true that it doesn’t help with the rodents. I’ve considered trying to mimic this project, but none of the sources are available…

  14. Pedrick says:

    Schrödinger’s cat could have used this to it’s advantage.

    I spy a thundercats logo!

    thunder, Thunder, THUNDERCATS, HOOOO!!!!

    The 90’s called they want their website and computers back…

  17. mlseim says:

    Pedrick: Schrödinger’s cat could have used this to it’s advantage.

    LOL! Maybe it’s in the house and outside at the same time. So you wouldn’t need the pet door?
    Hmmmmm …

  18. bogdanfirst says:

    This old project is very nice, but it should be improved:
    -add RFID so you don’t open the door to other cats.
    -make everything embedded, there are uC now that are powerful enough so you don’t “burn” all that electricity with a computer.

  19. CF says:

    Anyone else get completely annoyed when people do not RTFA.

  20. PocketBrain says:

    Yeah, el_walto, it’s a rerun. Featured here on Hackaday a few years ago.

    Here at “This day in History” we thrive at dredging up the very best of crap so old your parents were still kids when it happened.

    Check back tomorrow when we review the Rotary Phone Speed Dial apparatus.

    I brutally torture kill all the cats I can find in the hoods. You should invent some cat luring device to make my job easier.

    @catkiller

    иди јеби се

  24. plokko says:

    wow cutting-edge technology+cats=awwezome!!!
    i’m in ur cam haxxing ur face recognition!

    @catkiller
    NEDM!!!

    i’ll build the NEDM ultimate machine,i was building an helicopter with flamethrower,now i know why:
    it was ceiling cat asking me to build the NEDM ultimate machine!!

  25. cmholm says:

    @catkiller, if you’re racing off to google translate, you’ll want the serbian->(your language here) setting.

  26. wow. dude!!

  27. a says:

    FWIW, when cats bring you animals they are not being grateful or showing appreciation, they’re trying to teach you how to hunt, like a cat would teach its kittens in the wild. They expect you to play with the dead thing like you’re hunting it or chase it if it’s still alive.

  28. catkiller says:

    I’ve done extensive research into the cat killing field, and I’ve found that the most effective thing to do is to poison yourself severely and allow the strays to eat the toxic flesh of your rotting carcass.

  29. greycode says:

    Yeah, at least glance the article before you give us your “expert solution”. Unless you meant to give every rodent in the area an RFID, then RFID means nada.

    @mrgoogfan When using Google to give someone a well deserved direction, try for a language that won’t be misinterpetted.

    @catkiller You have had one too many disco biscuits.

  30. DudeGuy says:

    I remember this long ago too, but it was a great read, and i’ve thought about it from time to time. Thanks hackaday.

  31. ZooomPC says:

    Thats brilliant!

  32. Myrph says:

    So I guess you could kinda call this a CAT Scanner!

  33. j_at_chaperon says:

    Wow, I definitely ned this. My cats bring back alive and healthy rodents. I never chased so many mice and birds in my house since I have cats, which is a pity.

  34. hoschi says:

    you should continue to develope it and make a patent. thats if there isnt already one. who knows. good job.

  35. draeath says:

    @Unouhu

    You got it backwards.

    The cat is trying to teach you how to hunt, and starting from the beginning. Basically, the cat thinks you are on the ‘baby’ level.

    @j_at_chaperon

    Same deal as wil Unouhu, but you are a bit further along. The cat is confident you’d eat the rodent (so.. er, yea…) but doesn’t think you know how to hunt/kill.

    … animal behavior is fascinating :D

  36. Whatnot says:

    Odd concept to think a cat is teaching the person that supplied food its entire life thinking they needs teaching how to acquire food, flawed logic.
    In my experience cats bring it in as a social act and to ‘brag’, and because they like to play with their prey in a comfy safe environment.

  37. aardvarkoffnord says:

    I second Whatnot – our cat does bring in half-dead and fully alive prey, but he will not let you near it, it is his!.

    It once took three of us to separate him from a rat so we could dispose of it.

  38. walmeister says:

    Someday hack-a-dupe will be able to spot this using a quantum computing Schrödinger cat

  39. Alkzy says:

    This was definitely posted a few years back.

  40. moominply says:

    Been waiting for this to become a product for years, but now I’m looking at this as a prime candidate for a raspberry pi project…

  41. moominply says:

    Raspberry pi project anyone?

  42. Gravis says:

    archive.org shows that this page has not been changed since it was first crawled in 2000.

    seriously, this page is over a decade old. this should/could have been posted on day one of hackaday.

  43. Cletus says:

    So we rfid all the critter in the yard? Is that it?
