Lossless compression of images using minterm coding

Abstract

Lossless compression of images is important in fields like medical imaging and remote sensing. There are only a small number of good algorithms known to date for lossless image compression. We present a lossless image compression scheme which uses the concepts of logic coding and auto-adaptive block coding to obtain a scheme which performs comparable to the JPEG standard. The scheme reaches the best possible value of compression automatically, unlike the case of JPEG which gives a range of compression, based on available predictors.
