Tutorial 25: Tracking the Position of a Color in a Movie

There are many ways to analyze the contents of a matrix. In this tutorial chapter we demonstrate one very simple way to look at the color content of an image. We'll consider the problem of how to find a particular color (or range of colors) in an image, and then how to track that color as its position changes from one video frame to the next. This is useful for obtaining information about the movement of a particular object in a video or for tracking a physical gesture. In a more general sense, this technique is useful for finding the location of a particular numerical value (or range of values) in any matrix of data.
