What is the best way to detect Man Made Objects in images with natural background?

I'm trying to write an algorithm to detect man made object in the natural images, I found that many papers talking about detecting objects from the aerial view which is differ from what I want to do. If you have any suggestions or any ideas about this topic, please kindly share and thank you in advance!!

There are complicated algorithms that go way beyond the scope of what's discussed here so all I can do it to refer you to the algorithms and you can do a search for them. I think you'll want to look at "material detection" algorithms https://www.google.com/#q=material+detection+belief+map and "Main subject detection" (MSD) algorithms https://www.google.com/#q=main+subject+detection+belief+map. It's a new field that I think is just becoming of more interest due to proliferation of stock photography databases and CBIR (content based image retrieval). Sorry, but I don't have any MATLAB code for it.

Thank you for your reply! I was reading many topics about these concepts but unfortunately I got confused. I couldn't understand their methods well because they are not clear enough to me. Anyway, I appreciate your help and if there are any other ideas or suggestions please kindly share :)

Thank you!

Hi, I have worked on a very simple and lightweight system for segmenting natural and man-made structures in real-world scenes. It is described in the paper "Segmentation of natural and man-made structures by independent component analysis". I am sending the paper and code to your email.

Thank you for your reply! Could you please send the code to my email!?

Thank you for your consideration. I have searched about this paper and I found it. I took a quick look at it and it looks appropriate for my topic. I will read it again in details to see how can I use it to support my topic's progress.

Thanks again!
