The JPEG filename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a significant reduction of the file size.

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.
A JPEG image, according to Merriam-Webster, is "a computer file format for the compression and storage of digital images" or "an image stored in this format."
Stereo photography techniques are methods to produce stereoscopic images, videos and films. This is done with a variety of equipment including special built stereo cameras, single cameras with or without special attachments, and paired cameras. This involves traditional film cameras as well as, tape and modern digital cameras.
The JPEG committee was created in 1986 [11] [12] and the Joint (CCITT/ISO) Bi-level Image Group (JBIG) was created in 1988. [11] Former chairs of JPEG include Greg Wallace of Digital Equipment Corporation and Daniel Lee of Yahoo. Fumitaka Ono of Tokyo Polytechnic University was chair of the former JBIG group that has since been merged into JPEG.
JPEG XS (standardized as ISO/IEC 21122) is an interoperable, visually lossless, low-latency and lightweight image and video coding system used in professional applications.
