Image Formats

Overview

Typically, a digital image is a representation of a two-dimensional image as a finite set of digital values, called pixels. These are held in computer memory as a two-dimensional array of small integers, which are transmitted or stored often in a compressed form. Image file formats provide a standardized method of organizing and storing image data.
In this unit an overview on different image data formats is given, summarizing some characteristics and compression properties.
