Definition

Image compression is the process of encoding digital image information using fewer bits than an unencoded representation would use through use of specific encoding schemes.

Historical Background

Uncompressed image data is large in file size. To store or transmit the uncompressed image requires considerable storage capacity and transmission bandwidth. For example, for a uncompressed color picture file of 6,000 × 4,800 pixel (good for a mere 10 × 8 in. print at 600 dpi), number of bytes required to store it is 85 MB. Despite rapid progress in mass-storage density, processor speeds, and digital communication system performance, demand for image storage capacity and image transmission bandwidth constantly outstrip the technical progress. Image compression is therefore essential for image storage and transmission in most cases. In geographic information systems (GIS), images are generally...
