Hough Transform

Could anyone tell me about the Hough Transform to
perform fine edge detection in images?

I need to apply it in a Face Detection system.

Hi memset_0xfcbd,

I'm a new registered friend, and this is my first post.

The Hough Transform (HT) is an algorith used for shape detection such as linear HT to detect lines, circular HT to detect circles, ... etc. However, it cannot be used for edge detection. To perform edge detect, try one of the following
algorithm/operation:
- Canny edge detection: my favorite algorithm.
- Laplacian edge detection.
- Computing image gradient.

and ....... do your best in the project.

I'm glad you have answered me, HT. So you
can join my group if you want to. I'm using these image
processing algorithms to develop an iris recognizer in
Visual C++.

It's getting more interesting each time, but unfortunately
I can't seem to find the enough time to program it, I seem
to be very busy because of my University subjects and
homeworks.

So if you know about image processing, you would be
very helpful for us. Please write to one of my e-mail
addresses:

* memcpy_0xffcd@hotmail.com
* masm32_0f538h@hotmail.com
* ocnwtnsys32@yahoo.com

And tell me more about image segmentation, please.

Thank you for answering me, friend.
