   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. 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), with a newly designed, wavelet-based method.

   en.wikipedia.org/wiki/Lossless_compression

   Lossless compression. Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. [1] By contrast, lossy compression permits reconstruction only ...

5. Image file format - Wikipedia

   en.wikipedia.org/wiki/Image_file_format

   Image file format. An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy ...

   Anna Malgina/ Stocksy. “Catching up” on sleep over the weekend could reduce the risk of heart disease by 20%, a new study suggests. Sleep deprivation — often defined as less than 7 hours a ...

7. 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. Lossless JPEG was developed as a late addition to JPEG in 1993, using a ...
