GRAY CODES FOR PROGRESSIVE IMAGE COMPRESSION AND TRANSMISSION

Zita Klenovičová

   This paper presents the results of progressive image compression by bit planes. The grey level image is decomposed into a set of bit planes. The brightness of pixels was represented by a binary code at first and then by a set of Gray codes that can be generated from the original binary code. A new method for a set of Gray codes generation was proposed. For bit planes coding an arithmetic code was used and some experimental results in image compression are presented.

Keywords: image compression, progressive image transmission, Gray code, bit planes, arithmetic coding, Elias code
