By Ian Gilmour of Media Matters. From the abstract: Motion-JPEG2000 lossless data reduction is implemented as a key technology for reducing file size in storage and for reducing data rates in networked file transfer.

For many years, libraries and archives have used the JPEG and TIFF coding standards to store and make available images in an electronic format. Decades of research in image compression techniques as a subfield of signal processing have yielded advancements through the use of wavelet transformation (as opposed to JPEG which uses discrete cosine transformation and various competing standards for TIFF compression), and some have adopted products based on proprietary wavelet compression implementations such as SID. In the 1990s, under the auspices of the International Standards Organization and the standards section of the International Telecommunication Union, the Joint Photographic Experts Group worked to create a new imaging standard using wavelet compression. The work of the committee reached a pinnacle in December 2000 with the ratification of Part 1 of the JPEG 2000 standard.
