Code for the lab:

• For the lab, you'll need to implement the Canny edge detector in Pyro: You can find C code for the Canny edge detector here, along with a tutorial on the method.
• The person who wrote the above tutorial also for a Sobel and Laplacian edge detection tutorial, with C code

Cool web demo:

• A Canny edge detector demo on which you can change the parameters and rerun

Some links that might help you think about ways to compare edge detection methods:

• A web page that lists comparison articles
• A comparison study using human subjects

Some tutorial-like descriptions of different edge detectors:

• A description of different types of edge detection
• Another description of different types of edge detection
