Used for distribution (networking) and delivery (viewing), JPEG2000 was published in 2002 with the intention of superseding the original JPEG standard (created in 1991). Its most important features are greater compression for equal image quality and improved lossless compression. It is based on a wavelet compression scheme, resulting in compressed images that do not show the typical blocky JPEG artifacts. JPEG2000 images do show some blurring at very high compression rates. JPEG2000 is not widely supported in consumer photography at this time; however, it is often used for maps, aerial photographs, and medical imaging.
