An example of a piece of software implementing the Canny edge detection method, as described on the Wikipedia page.

• Zipped Windows binary, including LGPL licensed Qt libraries and some sample images for demonstration.
• Zipped Windows binary, without sample images.
• Source code, without UI design etc. [Licensing: You are free to do what you like with this source, so long as you link back to me, Carl Turner at suchideas.com.]
• Coming soon(?): full [still cross-platform] source, Linux binaries.

Please note that you must extract the full zip file into a folder to run the .exe (because I've attached the various shared Qt library DLLs needed to run the software). If there is any problem or suggestion you have, please contact me using the contact form, or via e-mail at carl AT suchideas DOT com. Thanks!

Warning: I am not responsible for anything that happens to you as a result of you using this software (or indeed this site). Be it upon your head.
