Lab Tutorial 0

When completing any lab it is useful to consider how the exercises relate to solving real world computer vision problems and how they could be extended and applied to your term projects.

Exercise 1: Matlab warmup

Familiarize (or re-familiarize) yourself with matlab. Be sure to understand basic concepts like the matlab workspace, matrices in matlab, operators including ' (transpose), * (matrix multiplication), .* (pointwise multiplication), and : (the very important colon operator). Also, an understanding of plotting, displaying images and requesting user input is important. Complete the following tutorial as a quick introduction to matlab. Here are more useful matlab links:
