What is a group of joint photographic experts?
A group of joint photographic experts, also known as JPEG, is a technical committee that develops image standards. JPEG is also the name of the Primary Standard of Group for Picture Compression - JPEG compression is widely used for images on the website and is supported by most editors, browsers and images. This standard is also used to compress and store images created mostly scanners and digital cameras.
In the early 80s. The International Standardization Organization (ISO) has created working groups to develop standards for photographic quality displays. In the mid -1980s, the ISO and the International Telegraph and Telephone Advisory Committee (CCITT) published the standards of images. In 1986, a group of joint photographic experts was created from participants within ISO and CCITT. This committee also created several JPEG standards for coding and compression of static images.
The related committee was created in 1988 from the same ISO working group, which created a group of joint photographic experts. This committee, known as a common group for Balance Balance (JBIG), focuses exclusively on binary images. A picture containing only two colors such as black and white is called a binary picture. The JBIG Committee is responsible for at least two standards regarding lossless compression of binary images.
Most of the implementations of the original common standards of a group of photographic experts include a certain degree of image quality loss. In general, the more the image is compressed, the greater the quality of quality. For this reason, this is called lossy compression. The use of a graphical editor for handling the JPEG image usually causes further quality loss every time it is modified. The full JPEG standard also includes lossless compression, but rarely isimplemented by Vweb applications.
Several standards were published by a group of joint photographic experts from the original publications at the beginning of the 90s. At the end of the 1990s, a standard called JPEG-LS was introduced to improve the original lossless compression method. It also includes a standard for compression that falls between losses and loss. The JPEG 2000 standard has redesigned the original compression method, increased performance and flexibility. The JPEG XR standard, introduced in 2009, includes improvements in compression, color accuracy and transparency.
Standards of a group of joint photographic experts are designed specifically for static images. In 1988, another ISO working group began to develop standards for video and sound compression. This committee became known as a group of experts in moving image (MPEG). Its standards are widely used to stream Internet video, digital television technology and digital video (DVD) with high -resolution.
