Term: JPEG 2000

The Joint Photographic Experts Group developed JPEG 2000 as an open imaging compression and file format standard (ISO/IEC 15444-1:2000) with the intention of superseding their original JPEG standard. JPEG 2000 is a wavelet-based image compression method that provides much better image quality at smaller file sizes than the original JPEG method. The JPEG 2000 file format also offers significant improvements over earlier formats by supporting both lossless and lossy image compression within the same physical file. A full range of metadata may also be bundled within the file. Since the JPEG 2000 format cannot be viewed within most Internet browsers, acceptance has been slow but its advantages are increasing its use by the cultural imaging community.
