Compression artifacts may intentionally be used as a visual style, sometimes known as "glitch art". Rosa Menkman's glitch art makes use of compression artifacts, [16] particularly the discrete cosine transform blocks (DCT blocks) found in most digital media data compression formats such as JPEG digital images and MP3 digital audio.

The Moving Picture Experts Group (MPEG) designed MP3 as part of its MPEG-1, and later MPEG-2, standards.MPEG-1 Audio (MPEG-1 Part 3), which included MPEG-1 Audio Layer I, II, and III, was approved as a committee draft for an ISO/IEC standard in 1991, [14] [15] finalized in 1992, [16] and published in 1993 as ISO/IEC 11172-3:1993.

MPEG logo Some well known older (up to 2005) digital media formats and the MPEG standards they use. The Moving Picture Experts Group (MPEG) is an alliance of working groups established jointly by ISO and IEC that sets standards for media coding, including compression coding of audio, video, graphics, and genomic data; and transmission and file formats for various applications.

A semiconductor technology, used to create photosensor arrays for some digital cameras. [4] CMYK: CMYK color model. A subtractive process for color printing that utilises cyan, magenta, yellow and black inks to create most printable colors. (Some colors can not be accurately reproduced using this system and require the use of "spot color" to
The most widely used lossy compression algorithm is the discrete cosine transform (DCT), first published by Nasir Ahmed, T. Natarajan and K. R. Rao in 1974. Lossy compression is most commonly used to compress multimedia data (audio, video, and images), especially in applications such as streaming media and internet telephony. By contrast ...

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.
