It's important to tune the parameters, then cany works very very well, &nbsp;pls see:<br />

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

I came across this post. &nbsp; I need to develop an &quot;edge detection&quot; program in C -- unfortunately, I don't have much programming experience.<br />
<br />
Any chance you'd be willing to share the code with me?<br />
<br />
Thousand thanks,<br />

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... <br />
<br />
Also, has anybody had many problems coding canny before?<br />
<br />
Many Thanks,<br />

Canny Edge Detection

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
