Abstract
Timely transmission of large format digital imagery over narrow bandwidth lines requires efficient and high compression of the digitized images. The techniques developed, Micro-Adaptive Picture Sequencing (MAPS), is a two-dimensional, spatial adaptive technique which uses the Redundant Area Coding (REARC) concept along with a very versatile algorithm developed by Control Data Corporation. Compression ratios of 30:1 have been achieved with MSE ranging from .548 to 2.534 percent for a broad variety of visible and radar imagery. (Author)
