Image representation; Pictorial metadata; Picture metadata
A digital image is a representation of a two- or three-dimensional image, where the representation can be of vector or raster type.
Metadata is data about data of any sort in any media, describing an individual datum, content item, or a collection of data including multiple content items. In that way, metadata facilitates the understanding, characteristics, use and management of data.
Image metadata is structured, encoded data that describes content and representation characteristics of information-baring image entities to facilitate the automatic or semiautomatic identification, discovery, assessment, and management of the described entities, as well as their generation, manipulation, and distribution.
Many of the techniques of digital image processing were developed in the 1960s at, among others, the MIT, Bell Labs, and the University of Maryland. These works tried to automatically...
