Questions tagged [jpeg2000]

JPEG2000 is an image encoded format intended to supercede JPEG.

JPEG 2000 is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard (created in 1992) with a newly designed, wavelet-based method.

JPEG2000 is supported by Webkit based browsers (Safari, Chrome) on Mac OS X.
