NSFW Artificially intelligent software is used more and more to automatically detect and ban nude images on social networks and similar sites. However, today's algorithms and models aren't perfect at clocking racy snaps, and a lot of content moderation still falls to humans.
Enter an alternative solution: use AI to magically draw bikinis on photos to, er, cover up a woman’s naughty bits. A group of researchers from the Pontifical Catholic University of Rio Grande do Sul, Brazil, have trained generative adversarial networks to perform this very act, and automatically censor nudity.
Paper - IEEE - International - Joint - Conference
In a paper for the IEEE International Joint Conference on Neural Networks (IJCNN) in Rio de Janeiro earlier this month, the eggheads presented some of their results. And it looks as though their AI code is quite hit or miss. Sometimes the computer-drawn bikinis don’t look realistic enough, and in some examples they are lopsided, too skimpy, or not well positioned to cover up enough skin.
At the moment, the project is more of a proof of concept. Rodrigo Barros, coauthor of the paper, told The Register on Thursday: “The approach described in our paper is an interesting and novel way of performing censoring on images. We believe that our approach for censoring nudity, in its current state, can't be applied practically simply because it isn't robust enough yet.”
Researchers - Dataset - Photos - Image - Packs
The researchers pulled together their dataset by downloading photos from “image packs via torrent files,” according to Barros. More than 2,000 images were collected, 1,965 were used for training, and the leftover 220 were used for testing the model.
Pictures of swimwear-clad women were fed into the system to teach it what a bikini looks like. To work out where the beachwear should be pasted, the software also had to be exposed to nude pictures. Armed with these photo sets, the software boiled down...
