Abstract: This report presents an overview of moving image (video) data compression. Because this report deals with a subtask of a major program, a limited number of the most pertinent topics and issues have been addressed. These topics include a listing of human perception effects and parameters for visual information; theoretical aspects of image data compression; a selective review of compression techniques; a closer look at motion detection, prediction and compensation; and a start to survey existing systems and their capabilities. Finally a multipage bibliography, while not exhaustive in any sense, shows the depth and breadth of the rapidly growing technology of image data compression.

Keywords: digital; prediction; data compression; images; motion compensation; visual effects
