You Have Too Many Pictures on Your Phone? Use Image Summarization!


In this activity, students will learn how to use mathematical optimization to aid in image summarization. In image summarization, there is a large collection of images and the goal is to find a small summary that consists of representative images. For example, for a collection with many images of a mountain and many images of a beach, a good summary would only keep a single mountain image and a single beach image. The activity will be divided into two parts. The first part will focus on how to formulate the problem of image summarization as a mathematical problem. The second part will focus on an algorithm for solving image summarization.
