Detecting Nudity With AI and OpenCV

Posted by ryuzaki0 on from the swapping-out-the-interns dept.

mikejuk writes: AI gets put to some strange tasks. Not satisfied with the Turing test or inventing Skynet, Algorithmia have put together a nudity detector. Take one face detector from OpenCV and use it to find a nose. Take the skin color from the nose and then see what parts of the body are skin colored in the photo. If there is lot of skin color shout NUDE! Actually, the website lets you put in your own photos and classifies them into Rude or Good and gives you a confidence estimate. Obama with his top off — no problem but the familiar image processing test photo of Lena the pin up girl rates a 'Rude'.

      anyone using such technology would require an extremely low false negative score... but too many false positives can make the system unusable. one of my last projects at undergraduate university was pretty much the exact same "nudity confidence" test as this project... my project "worked pretty well" also, but was equally unusable. i dialed all the parameters for a week until i got the best results on a giant dataset (millions of images)... one of the sources of images was every image from the university website (over 10,000 images just from that). so, after the tweaking, false negatives were low, but still 5% of negatives were wrong. i don't remember exact numbers, but i think of the positives, 10-15% of those were wrong. i didn't use any libraries or facial recognition, but i imagine that would help a lot... one problem is obviously if the face isn't in the picture. my technique was using a wide range of skin tones and then looking for "blobs" of similarly toned pixels and looking for shapes or shapes in shapes... (nipples on breasts were a pretty solid indicator and easy to scan for... also detecting a crotch region with dark hair... obviously a fat man in a hair-toned thong would trigger alarms)

      so, after all of this, many variables are weighted to give a single "confidence" score... so i decided to run the test a final time before the presentation the next day (it took many hours to run)... i built lots of top lists, one of them was overall confidence of nudity... the #1 picture most confident of containing a nude body ended up being the faculty office picture of one of the lecturers in the computer science department, who would be attending the talk. the office walls were a skin tone, and the way the light came in the window and lined up with her head, and round shaped things on her desk reflecting the skin tones, triggered every single test i had built. out of millions of pictures... too funny. good closer for the presentation.

Any position where the legs are in front of the body (like hugging knees) will come through as nude even if they are fully clothed, shoes are not counted as clothing, so it has a VERY high false positive rate. If one of the fascist bastard places like Facebook or Instagram were to use it they would end up punishing a lot of people who didn't even violate terms.

    Someone I know was tasked with catching people at work watching porn. So.. they screen grabbed everyone occasionally and checked manually. That got tedious so an algorithm was scripted to scan the photos for slightly darker circles within larger circles (breasts).... the person that wrote that code no longer has a job there because they just run the program and don't need to manually check X.x

    It doesn't have to catch every concurrence of course.. just enough to flag culprits with few false positives. Also, don't code yourself out of a job!

    Thing here has really high false positives, most of the time it flags faces as nude.

His sitters included three American Presidents, nobility, the Swedish king and queen and numerous members of high society."). You can scroll down a bit on the wikipedia page to see examples of images that were considered so "rude" that they led to the banning of a government-funded art institute.

    My assumption is that this was done by a bot rather than a real person, probably based by a similar technology as in the OP, because I can't believe even facebook censors are that stupid.
