ABSTRACT
Images are natural and efficient conveyors of information and have been used throughout history as models for both reality and abstract concepts. Our appetite for visual information seems insatiable, and efficient image management continues to be of pressing concern. An image can contain a large amount of information (more than a thousand words?) and often translates to a data structure whose large size can pose problems to storage and transmission management. The situation only gets worse when several images or animation is involved.
