well even i am into image processing and this link helpmed me a lot .
i dont know how far it will help you .

The following link describes in detail how to code edge detection yourself:
http://www.pages.drexel.edu/~weg22/edge.html
And maybe this link is useful too: http://www.intelliproject.net/articl...oc_edge_detect

l seen soemthing like this in the OpenCV libraries.

Yeah, I just wanted to say that: http://opencv.willowgarage.com/wiki/Welcome

Thanks for your posts, but none of those libraries provides what I want.

It's not working under Dev Cpp, under Builder it generates white image.

OpenCV is too exotic and weird. Provides many files but there is no good documentation and examples for Builder c++. I couldn't run it properly.

There is no edge detection in this library.


I'm still searching ...

And what about this one ?
Or this one ?

So far it seems there isn't a library which supports it so you'll maybe have to implement it yourself ...

well may be these underneath links might help you .

First of all: OpenCV is not exotic or weird. It is actually being used a lot, even by professional companies.
The reason that there are so few examples for Borland Builder, is that Builder is outdated and there are plenty free (and better) alternatives on the net. (like VS2008 and Code::blocks)

But you are probably going to say: "But I like Borland, I don't wanna change!1!" etc. So here's a link with a manual and even a demo-project. I found it using this amazing site.
