JPEG 2000
Appearance
The Joint Photographic Experts Group committee has created its own wavelet-based image compression standard, JPEG 2000, which is expected to eventually supersede their orginal discrete cosine transform-based JPEG standard.
JPEG 2000 can operate at higher compression ratios without generating the characteristic 'blocky and blurry' artifacts of the original DCT-based JPEG standard.
JPEG 2000 is not yet widely supported in web browsers, and hence is not generally used in the World Wide Web.
