Nude image detection - OPENCV - Machine Learning [

问题:

I'm trying to implement software which automatically detects nude images. Hoping to do this through openCV. What do you think of the possibility and the best algorithm that can be used? Any examples would be highly appreciated.

回答1:

Depending on how accurate it needs to be you could just define a reasonable colour space that covers flesh tones, and then have some % threshold whereby if the flesh tone pixel count exceeds this % threshold then it may well be a nude image.

You may want to keep an eye on this site. This is what chatroulette uses. It targets, ahem selective nudity, but it may be related to what you're after.

There's a downloadable demo (so far, without source).

Have you considered a neural-network approach? What you're asking for sounds like a machine-learning application.
