2. Image compression - Wikipedia

   en.wikipedia.org/wiki/Image_compression

   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 ...

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.

4. Lossless JPEG - Wikipedia

   en.wikipedia.org/wiki/Lossless_JPEG

   General description. JPEG-LS is a lossless or near-lossless compression standard for continuous-tone images. [6] Its official designation is ISO-14495-1/ITU-T.87. [7] It is a simple and efficient baseline algorithm which consists of two independent and distinct stages called modeling and encoding.

5. 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.

6. 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 ...

7. Lossless compression - Wikipedia

   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 ...

8. JPEGmini - Wikipedia

   en.wikipedia.org/wiki/JPEGmini

   JPEGmini technology is built around a perceptually aligned image quality measure, which reliably determines the maximum amount of compression which can be applied to each individual image or video frame without introducing visible artifacts. This engine does the image transformation and generates an output that complies with all standards when ...

9. JPEG XR - Wikipedia

   en.wikipedia.org/wiki/JPEG_XR

   JPEG XR is an image file format that offers several key improvements over JPEG, including: [ 16] Better compression. JPEG XR file format supports higher compression ratios in comparison to JPEG for encoding an image with equivalent quality. Lossless compression. JPEG XR also supports lossless compression. The signal processing steps in JPEG XR ...
