Hello folks,

I've been wondering every now and then where could I find human-readable descriptions of algorithms for detecting shapes (e.g. lines) from images. Google already found this very nice tutorial describing a couple of edge detection algorithms but I'm still missing a way to detect the geometries (this is a line, there's a rectangle, that's a circle over there, etc.) the "edge pixels" form.

I would really appreciate any pointers...

During my studies at EPFL I took a course about pattern recognition. Unfortunetaly, the whole stuff is in French, but here is a cool book:
Image Processing, Analysis and Machine Vision 2nd
Milan Sonka, Vaclav Hlavac et Roger Boyle
PWS publishing, 1998

Here are some pointers at McGill for pattern recognition.

There is also the RAVL project at sourceforge, which is a C++ library for computer vision and pattern recognition.

Hope this helps...

Thanks, Valentin! There's a lot of links to go through. Especially this tutorial about the Hough transform looks promising.

I'm not sure but maybe JAI could help also...

Look up JOONE on the Internet (Java Object Oriented Neural Network). This is the way to recognize patterns.
