    JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.

  3. Lossless JPEG - Wikipedia

    en.wikipedia.org/wiki/Lossless_JPEG

    JPEG 2000's lossless mode runs more slowly and has often worse compression ratios than JPEG-LS on artificial and compound images [12] [13] but fares better than the UBC implementation of JPEG-LS on digital camera pictures. [14] JPEG 2000 is also scalable, progressive, and more widely implemented. [citation needed]

  5. Image file format - Wikipedia

    en.wikipedia.org/wiki/Image_file_format

    JPEG 2000 is a compression standard enabling both lossless and lossy storage. The compression methods used are different from the ones in standard JFIF/JPEG; they improve quality and compression ratios, but also require more computational power to process. JPEG 2000 also adds features that are missing in JPEG.
