I want to write a program that processes images.
If there are good algorithm libraries in object extraction that would save me a lot of work.
anybody?
are there any good libraries in image processing?
I am willing to use c++ or c# whatever has good libraries.
Thanks

Try out OpenCV.

This depends on your focus in image processing.
If your focus is image processing on digital camera images, I would suggest using OpenCV (as already mentioned by #ffriend). If your focus is image processing on radiological images (MRI, CT, etc.) I would suggest using ITK for the processing algortihms and VTK for rendering.
All those libraries are written in C++. Some have interfaces to scripting languages like python.
Hope this helps for a start!

Does anybody knows which are the best tools for image segmentation?
I'm starting to do a project that evolves in a specific GUI to recognize some parts of the image such as a button, or a text box for example.
Can anybody tell me which sould be the easiest and the most efficient tool for this kind of issues?
Thank You.
Though your question may not be well posed, there are several tool kits for image processing.
One option is OpenCV. This computer vision library can perform a wide range of operations from simple image processing to object recognition for robotics. Here is one quick image segmentation example, straight from the documentation.
This library is powerful, but it may not suit your application. Please consider asking a more specific, technical question.
There are a few toolboxes for pattern recognition in images>
in matlab you can find: https://www.mathworks.com/matlabcentral/fileexchange/46392-pattern-recognition-toolbox
It is called PRTools> http://prtools.org/
and this is for more statistical purposes rather than segmentation>

If you deal with neuroimages, you can then take a look on>

I search a win32 wrapper libraray that completly isolate me from the api.
I only want to create a opengl 3.3 window for windows only.
I know there are libraries like GLFW, SFML and SDL but this libraries are to large and heavy.
Know someone one?
I could suggest you to use Qt library, but you would also complain because of the size of the dlls.
I'm afraid you won't find easily such lightweight library.
Using Win32 SDK for creating an OpenGL application is not that difficult. As for an experienced Win32 developer, I insist that it's even really easy.
It's always the same program structure, same messages handled, same function calls (loop, threads etc).
Please have a look on the internet for the OpenLG SuperBible tutorials.

Is there a simple (and fast) toolkit for drawing things on a canvas (e.g. circles, lines, rectangles)?
It would be best if it was in Python, Java, C++.
I'm trying to make an application that drag'n'drops items to a canvas and moving them around in the canvas.
I've looked at a few, pyglet, Java Swing, HTML5 or are there other ones more suitable?
Take a look at the Qt's(C++ toolkit, there are also Python bindings - PyQt & PySide) Graphics View Framework.
And here are some examples.
Hope this helps
If considering HTML5 Canvas, I would take a look at Processing.js.

Are there any 3D assets like windows, list boxes, etc. that can be used in a 3D game engine?
Something like Age 3D is a great start, http://www.youtube.com/watch?v=Cq8Qs8lqqFA, but they aren't around anymore.
Something like Crazy Eddie's GUI System?
You might want to look at FLTK. Definitely still in development -- the most recent weekly snapshot was released today.
Qt allows all GUI elements to drawn into an OpenGL viewport.

Does anyone know what open-source library Google uses for its Google Similar Image?
I need to find the similarity of two images of different sizes but slightly similar content. I need to get a metrics value.
Have you looked at SourceForge or Google Code?
This project looks very good. And the tag ImageProcessing has 249 hits. Surely you will find something there.
Btw, do you have any requirements w.r.t. OS, programming language, etc?
