Wow. Just, wow.

You really don't have any clue what you commited yourself to, do you? Google for "Machine Vision" or "Machine Vision Pattern Matching" and start reading.

Desperate? How far have you gotten?

hi dave,

thank you for your advice, i will start reading "machine vision" now.Actually i have an idea to filter images using plugins but you are right i still don't have any plan how to start it. =(

"computer vision" will also give some good results, the OpenCV library might be of interest.
That said like Dave and Albert has said, this is a massive undertaking, hell this is still an area that is being heavily researched all over the world. And you should expect to at least spend 2 years studying computer vision, before you can even start to create something that would have a decent success rate and a low false positives rate.

When I worked at a university... we had a guy who's whole career focused on digital image processing... he developed algorithms that would identify people in video (versus other object, moving or otherwise). His algorithms were very impressive, not surprisingly, his research was well funded by govt.

Yeah, I've seen some people detection/tracking algorithms in action on youtube and I'm impressed by the high accuracy, but the OP want to go one step further, to detect whether or not they have clothes on, well it's not even that easy they can have plenty of clothes on in a pornographic picture. To me it seems like a life long en devour that far from guarantees success.

The various problems you have is that you can detect human shapes in various poses, but not all poses. How are you going to determine what these people are doing? Clothed or not doesn't give you any reliable indication of what's going on.

You said you were desperate. Is this something you have to turn in for a project? If so, you won't be handing it in for about the next 30 to 40 years.

That's a rather advanced digital imagery problem. A simple way to start off would be to filter images based on image names (look for keywords), but after that, you'd have to interpret the image and look for patterns (a rather advanced subject). One approach would be to look at facial recognition algorithms and see if you can modify them to search for particular shapes. Now keep in mind, there's people that dedicate a lot of time and entire careers to developing these algorithms, so it may not be no simple task to "tweak" them.
