JPEG 2000

Abstract

JPEG 2000 Part I which has become an international standard (IS) in December 2000 is reviewed. Parts II to VII relating to extensions, motion JPEG 2000, conformance, reference software, file format and technical report are in various stages of development with IS targeted for the year 2001. JPEG 2000 focuses on efficient coding of grey level and binary still images (compound documents, text, annotation, multi-component, and rendered graphics). JPEG 2000 is superior to the widely popular JPEG and addresses various functionalities and services. It is aimed at emerging technologies such as Internet, E-commerce, mobile multimedia, color facsimile, and digital libraries while providing user controlled bit rates, quality levels and scalabilities (both SNR and spatial). It has lossy, lossless and progressive lossy to lossless modes. Algorithmic operations that constitute the JPEG 2000 standard are presented. Performance evaluation of this new standard and comparison with JPEG and JPEG-LS are discussed.
