Lecture 25 (Edwards) - Edge Detection and Image Difference

Lecture Date: Monday, April 20

Today we will talk about how to detect edges in an image and image difference.

We can think of edge detection as figuring out when adjacent pixels change color by a sufficient amount. What’s sufficient, that’s up for use to decide.

Image difference is looking at two pixels of supposedly similar images and seeing if we can spot a difference.
