An API based on machine learning and few other algorithms for better precision. Opened for public BETA 2 weeks ago, would appreciate an honest opinion of its inner workings.

  I actually have a need for this in a new project, I'll be showing it to the team tomorrow. This is a great idea. I tested it with a bunch of pictures and it was perfect.

    Thanks greggh, it's great to hear. Drop me an email through the contact page if you have any questions or need help with anything regarding the API, I'll be glad to guide you setting it up if there is a need for that. On a side note, what programming language would you be using to communicate to the API? We have Python and PHP libs on github already, NodeJS in the works.

It does not work on Firefox: TypeError: $ is not a function $( document ).ready(function() { Maybe jQuery is loaded too late?
- jusob 10y ago
  Also, the documentation seems to describe the requests only, but not the response.

    Thanks for reviewing! I am unable to replicate a problem in firefox as it works for me now, but I'll try different versions and fix it if I happen to come across it. That's a valid point on the documentation, we have only included the raw json response for each endpoint, I'll write descriptions for each field in them. Thanks!

do you log user activity or do i have to report mismatches manually? edit: either way i suggest adding a feedback button so that users can teach the neural network. - edit#2 example: http://www.kenya-today.com/wp-content/uploads/2014/11/chicken.jpg http://www.kenya-today.com/wp-content/uploads/2014/11/chicke... and http://earhustle411.com/wp-content/uploads/2015/10/recalled-chicken.jpg http://earhustle411.com/wp-content/uploads/2015/10/recalled-...

  Oh this is a huge help that you found this situation now. The last one - horses bodies - was the same, oval shape and skin with veins. I do seldomly check the sandbox queue of images looking for those situations. But I do not know about the user taught neural models. You can't trust the internet to teach your AI as microsoft lately shown us. But I will implement some kind of reporting system. Thanks ilovecocacola!

Wow, I'm really blown away at how accurate this is, particularly how well it was able to discern between nudity and covered nudity. Only odd thing I noticed was that male torsos were flagged for nudity. Is that intentional?
- gsso 10y ago
  Thanks so much! It's semi intentional. We are constantly working on the deep learned models twitching and improving them as we go and the one in the API workers right now is stable, accurate, but doesn't have few major categories learned yet. The newest one knows the difference between female and male torso, and will flag a male torso accordingly - probably increasing a "covered nudity" confidence as it appears.

    Congratulations, it seem to be pretty accurate. But it looks like it has problems with b/w pictures? Example: http://images2.gazzettaobjects.it/methode_image/2014/11/25/Varie/Foto%20Varie%20-%20Trattate/Lear%201971-k4rG-U10049725290lTB-620x349@Gazzetta-Web_articolo.JPG?v=201411251333 http://images2.gazzettaobjects.it/methode_image/2014/11/25/V... returns: { ... "data": { "covered_nudity": { "confidence": 1, "result": false }, "nudity": { "confidence": 1, "result": false } } }
    - gsso 10y ago
      Thanks! That's a great find, I'll add it to the test images. It might be b/w, it might be that shadow above the breast, I'll check and let you know. Usually b/w images passed the tests well, I might have not have enough in the test sets.

could you please tell me if my previous comment was inappropriate/violates the guidelines? i'm new here. it confuses me that you replied to everyone except me.

  It got hit by a spam filter. Sorry about that; those are tuned more aggressively for new accounts. We've marked your account legit so it won't happen again.
