Last time we learned how image detail affects the ability to understand what we see. A way to quantify image detail is resolution, which tells us how close together two details can be, such as the dots in images from last class, before the gap between them seems to disappear. Today we will learn how this definition of resolution ties into everyday life, such as the resolution of computer and cellphone screens, by studying the properties of identical images from online but of different resolution.
