I was wondering if anybody could point me in the direction of some code for the canny edge detection. I'm doing a project to include all types of image edge detection and I have done a good few all ready, like sobel, roberts, robinsons, prewitt etc. but I can't seem to get the canny detection working...

Also, has anybody had many problems coding canny before?

Many Thanks,
Tech_ie

Thanks Manirup, I looked at that code and I saw that I was going wrong in the gaussian filter part of canny...

manirup:

I came across this post.   I need to develop an "edge detection" program in C -- unfortunately, I don't have much programming experience.

Any chance you'd be willing to share the code with me?

Thousand thanks,
EEH
