Hi!
This file is very easy to use!
Hope it helps to perform your work.
Main description points:
1. In this file, you first should open main.m and setup desired threshold levels.
2. As a demo, for the given puppy.jph image, the parameters were set up.
3. To smooth the image, Gaussian 3 by 3 kernel was used.
4. If you want to see all the code as one script, just run cannyInOne.m file.
5. Code is not commented, but refer to Report or Presentation of this archive.

Good luck!
