The patterns are referred to as the two-dimensional DCT ''basis functions'', and the output values are referred to as ''transform coefficients''.

Definition

file type
<file format> The kind of data stored in a file. Most modern operating systems use the filename extension to determine the file type though some store this information elsewhere in the file system. The file type is used to choose an appropriate icon to represent the file in a GUI and the correct application with which to view, edit, run, or print the file. Different operating systems support different sets of file types though most agree on a large common set and allow arbitrary new types to be defined.

JPEG

JPEG ( JAY-peg, short for Joint Photographic Experts Group) 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. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015.

The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet and later social media.

JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished and are simply called JPEG.

The MIME media type for JPEG is "image/jpeg," except in older Internet Explorer versions, which provide a MIME type of "image/pjpeg" when uploading JPEG images. JPEG files usually have a filename extension of "jpg" or "jpeg." JPEG/JFIF supports a maximum image size of 65,535×65,535 pixels, hence up to 4 gigapixels for an aspect ratio of 1:1. In 2000, the JPEG group introduced a format intended to be a successor, JPEG 2000, but it was unable to replace the original JPEG as the dominant image standard.
