I'm looking for some library that will allow me to identify black dots on a white background. Preferably in C or objective-c.
Also, what keywords can I use in my search for such algorithms? I've found a lot of stuff about image recognition but nothing that ressembles what I'm looking for.
thanks!
I think there is a possibility to use OpenCV in obj-c
The general API can be found at: http://opencv.willowgarage.com/
OpenCV vs. Apple iPhone article shows 2 approaches to get OpenCV on iPhone, may be what you're looking for.
You can try imagemagick.

I'm trying to make a fractal image in C. What is the best way to convert a computed matrix to an image? Is there a built-in library or must I use an external one.. if so any suggestions?
The GD library is basic but still quite useful. (It's embedded into the PHP language.)
Or, if you don't want to rely on external libraries, output your data to a text format like PPM, and then convert it to a different format in your favourite graphics editor (or a tool like ImageMagick).

Does anyone have a Gnome GDK example code or tutorials?
I know that this is getting annoying, considering so many people ask this but I've tried and tried finding a Gnome GDK tutorial, for like an hour or so and I still don't have any luck, I'm using only C programming language, thank you.
Probably you have stumbled over the GDK Reference Manual already but did not scroll down far enough to realize that there are actually many examples in there:
https://developer.gnome.org/gdk/2.22/
E.g. click on windows then scroll down to example 7.
113 line tutorial right there, hope this helps.

I want to learn how C is interpreted,
anyone knows where to download it?
http://www.thefreecountry.com/compilers/cpp.shtml
I found that in about 10 seconds using Google. You can too.
A good basic compiler suitable for getting an intro to the subject and including sources is tinyc. It is capable of being used in a similar manner as an interpreter, too (unlike GCC et al).
http://gcc.gnu.org/releases.html
Try this:
http://en.wikiversity.org/wiki/C
and this:
http://gcc.gnu.org/

I need to do some work with this library and I'm finding the documentation at http://apodeline.free.fr/DOC/libjpeg/libjpeg.html to be deficient (incomplete function signatures, etc). Does anyone know of some other sides or have some example code illustrating common tasks?
[Edit]
I also found this question with an example, but any others would be helpful.
Try using libjpeg library. Example how to use it is in this blog.
I don't know what you're using, but we use the C++ wrapper at Smaller Animals Software, and we're happy with it. If nothing else, it might work as example code.
