Following this tutorial, you will learn how to use EasyImage to transform a gray-level image to a binary image, keeping only the edges detected in the image. The conversion uses the Canny edge detector algorithm.

You'll need to load a source image (step 1), and simply apply the Canny edge transformation (step 2).
