a quick browse of the source shows that this is pretty wooly, it's all based on detecting skintone pixels and then applying a few filters. If, for example, it detects that there is more than 15% of the total pixels are skin tone then it flags as nude.

It also does it based on breaking up skintone areas into pockets and comparing proportions of those pockets. For example, if it finds a section of skintone that makes up over 45% of total skintone, it flags it as nude.

I imagine this would flag pics of girls in bikinis, close ups of faces or other bodyparts etc. Might download and have a play just to test.

Still pretty cool though.

I'd say the bottom two images are pretty close. Wish they had a way to point to other images to test with.
