2. 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.

3. Image file format - Wikipedia

   en.wikipedia.org/wiki/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 compression or ...

4. 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.

5. JBIG2 - Wikipedia

   en.wikipedia.org/wiki/JBIG2

   JBIG2 is an image compression standard for bi-level images, developed by the Joint Bi-level Image Experts Group.It is suitable for both lossless and lossy compression. . According to a press release from the Group, in its lossless mode JBIG2 typically generates files 3–5 times smaller than Fax Group 4 and 2–4 times smaller than JBIG, the previous bi-level compression standard released by

6. Lossless JPEG - Wikipedia

   en.wikipedia.org/wiki/Lossless_JPEG

   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 ...

7. Data compression ratio - Wikipedia

   en.wikipedia.org/wiki/Data_compression_ratio

   A compression ratio of at least 50:1 is needed to get 1080i video into a 20 Mbit/s MPEG transport stream. Uses. The data compression ratio can serve as a measure of the complexity of a data set or signal. In particular it is used to approximate the algorithmic complexity. It is also used to see how much of a file is able to be compressed ...
