In computer science, the representation of an image can take many forms. Most of the time, it refers to the way that the conveyed information, such as color, is coded digitally and how the image is stored, i.e., how is structured an image file. Several open or patented standards were proposed to create, manipulate store and exchange digital images. They describe the format of image files, the algorithms of image encoding such as compression as well as the format of additional information often called metadata. Differently, the visual content of the image can also take part in its representation. This more recent concept has provided new approaches of representation and new standards, gathered together into the discipline named content-based image indexing.

Historical Background

The first use of digital images began in the early 1920s with the technological development of...
