  2. JPEG - Wikipedia

    en.wikipedia.org/wiki/JPEG

    JPEG. JPEG ( ⫽ ˈdʒeɪpɛɡ ⫽ JAY-peg, short for Joint Photographic Experts Group) [2] is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.

  3. Lossless JPEG - Wikipedia

    en.wikipedia.org/wiki/Lossless_JPEG

    Lossless JPEG is a 1993 addition to JPEG standard by the Joint Photographic Experts Group to enable lossless compression. However, the term may also be used to refer to all lossless compression schemes developed by the group, including JPEG 2000, JPEG-LS, and JPEG XL .

  4. JPEG 2000 - Wikipedia

    en.wikipedia.org/wiki/JPEG_2000

    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 ...

  5. Image compression - Wikipedia

    en.wikipedia.org/wiki/Image_compression

    Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.

  6. Lossy compression - Wikipedia

    en.wikipedia.org/wiki/Lossy_compression

    Lossy compression. In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content.

  7. JPEG XL - Wikipedia

    en.wikipedia.org/wiki/JPEG_XL

    JPEG XL is a royalty-free raster-graphics file format that supports both lossy and lossless compression. It is designed to outperform existing raster formats and thus become their universal replacement.

  8. JPEG XS - Wikipedia

    en.wikipedia.org/wiki/JPEG_XS

    JPEG XS is a light-weight compression that visually preserves the quality compared to an uncompressed stream, at a low cost, targeted at compression ratios of up to 10:1.

  9. Compression artifact - Wikipedia

    en.wikipedia.org/wiki/Compression_artifact

    Compression artifact. A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted ...
