There are several excellent books:

Hello!

The computer vision topic is very interesting for me and I read about it, and even think to make something in this direction. I have an applied mathematics background but I am not familiar with the theory behind computer vision techniques. When I try to read it I cannot understand much. I believe, the programming algorithms are not so complicated as the theory describes. Is there any tutorial for dummies about these techniques?

I was also curious what methods are used for shapes recognition. In my task I implemented rather simple algorithm to determine straight pieces from a curved line described by a set of points. But I am looking for something which can help me to find also other shapes (including self-defined). Please give me a tip or a link.

Thank you.
Regards,
Alexandr

You can also look at the free ImageJ software and a Java cookbook http://www.lac.inpe.br/JIPCookbook/index.jsp

Dear Matvey,
Thank you for the information. I first would like to read some theory on this topic but the software is also interesting and I will look at it later.
What do you do on this subject? Can I see your work somewhere?
Regards,
Alexandr.

You can find my research papers on Google (both medical and CS). Those having the code inside are waiting for publication.

I spent several years programming and image processing, because it was a part of my job,

I can share with you my experience, if you need.

You know, Mahotas/Numpy is a beautiful Python library to play with images. Once things are installed, you can rapidly develop the code for the tasks you need. From my experience it works better on Ubuntu 11.04. Cammelia, VTK/ITK and OpenCV are more complex and fragile libraries, especially when using C++. You can attach Qt, Wx or GTK/FLTK GUI for your applications with Python and produce a good software (if your are not afraid to become blind and sick from sitting too long...)

Dear Matvey,

Thank you for the information. This is a new topic for me and it will take some time until I reach the programming phase. I am neither familiar with GUI development which is also a time consuming study for me. So, your experience will be very appreciated.

I see many terms in this subject which are not known to me, like surf, watershed, thresholding etc. I think I need first to learn more about them and I would like to start from something which is easy to understand. What would you recommend me to read as for the newcomer? Only one source...
