Abstract

A new technique for image compression and/or enhancement is presented. The method comprises dividing the two-dimensional spectrum into low- and high-frequency components and digitizing the latter with a tapered, randomized quantizer. A version of the system in which the highs component is adaptively adjusted gives improved picture quality.
