The Joint Photographic Experts Group is the joint committee between ISO/IEC JTC1 and ITU-T (formerly CCITT) that created the JPEG, JPEG 2000, and JPEG XR standards. It is one of two sub-groups of ISO/IEC Joint Technical Committee 1, Subcommittee 29, Working Group 1 (ISO/IEC JTC 1/SC 29/WG 1) – titled as Coding of still pictures. In the ITU-T, its work falls in the domain of the ITU-T Visual Coding Experts Group (VCEG). ISO/IEC JTC1 SC29 Working Group 1 (working together with ITU-T Study Group 16 – SG16 and previously also with Study Group 8 – SG8) is responsible for the JPEG and JBIG standards. The scope of the organization includes the work of both the Joint Photographic Experts Group and Joint Bi-level Image Experts Group.
In April 1983, ISO started to work to add photo quality graphics to text terminals. In the mid-1980s, both CCITT (now ITU-T) and ISO had standardization groups for image coding: CCITT Study Group VIII (SG8) – Telematic Services and ISO TC97 SC2 WG8 – Coding of Audio and Picture Information. They were historically targeted on image communication. In 1986, it was decided to create the Joint (CCITT/ISO) Photographic Expert Group. The JPEG committee was created in 1986. In 1988, it was decided to create the Joint (CCITT/ISO) Bi-level Image Group (JBIG). The group typically meets three times annually in North America, Asia and Europe. The group often meets jointly with the JBIG committee.
JPEG (/ˈdʒeɪpɛɡ/ JAY-peg) 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.
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 term "JPEG" is an abbreviation for the Joint Photographic Experts Group, which created the standard. The MIME media type for JPEG is image/jpeg, except in older Internet Explorer versions, which provides a MIME type of image/pjpeg when uploading JPEG images. JPEG files usually have a filename extension of .jpg or .jpeg.
An expert ( pronunciation (US) ) is "somebody who obtains results that are vastly superior to those obtained by the majority of the population". Alternatively, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credential, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opinion. Historically, an expert was referred to as a sage (Sophos). The individual was usually a profound thinker distinguished for wisdom and sound judgment.
Group may refer to:
A joint or articulation (or articular surface) is the location at which bones connect. They are constructed to allow movement (except for skull, sacral, sternal, and pelvic bones) and provide mechanical support, and are classified structurally and functionally.
Joints are mainly classified structurally and functionally. Structural classification is determined by how the bones connect to each other, while functional classification is determined by the degree of movement between the articulating bones. In practice, there is significant overlap between the two types of classifications.
Terms ending in the suffix -sis are singular and refer to just one joint, while -ses is the suffix for pluralization.
An articulate facet is generally seen as a small joint, especially used when speaking of the joints of the ribs.
Structural classification names and divides joints according to the type of binding tissue that connects the bones to each other. There are three structural classifications of joints:

JPEG (Joint Photographic Experts Group) (jay-peg) 1) A computer format for recording still, color images, particularly photographs with millions of colors. 2) A computer files saved in this format. What is the compression of JPEG? JPEG Compression is the name given to an algorithm developed by the Joint Photographic Experts Group whose purpose is to minimize the file size of photo- graphic image files. JPEG compression is a powerful tool, and with great power comes great responsibility. JPEG 2000 (JP2) is an image compression standard and coding system. It was created by the Joint Photographic Experts Group committee in 2000 with the intention of superseding their original discrete cosine transform-based JPEG standard (created in 1992) with a newly designed, wavelet-based method.

A JPEG is an acronym for the Joint Photographic Experts Group, it is an international standard for bitmapped coloured images. The nice thing about a JPEG is that the user can define the degree compression from high quality to low quality. JPEG typically achieves a 10:1 compression with little perceptible loss in image quality. Reference: http://en.wikipedia.org/wiki/JPEG Created at http://goanimate.com/
Lossy vs. lossless image file formats For better utilization of storage space, utilizing the bandwidth efficiently over the internet and for more other reasons images are going to be compressed and decompressed several times. When we compress an image some of the data is going to be removed from the image, hence automatically image size reduces on compression. To get back the original image, on decompression the removed data is going to be added back to compressed image. That means once we compress an image, we can reconstruct the original image from compressed image. There are two types of compression algorithms, which perform these tasks. Lossless compression algorithms: Allow the original image to be exactly reconstructed from the compressed image. No loss of data. No loss of quali...

The old Dniepr Memory (Translation of the Ukrainian text of the film into English) It is always very interesting to know something about history of the native country, about what was happening here on the Dniepr bancs in the ancient times. Except scientists (historians, archaeologists, geologists and paleontologists) some other people tray to solve this mystery. They are amateurs – people, who do wish to discover and announce to their compatriots knowledge about ancient history of their native country. The film is a trial of one of such amateurs to reconstruct as far as it is possible the mental pictures of the life which took place on the Dniepropetrovsk region territory during glacial period and earlier. In 1996 together with his friends he made an exhibition named “The Great River Mem...

JPEG es un algoritmo de compresión con pérdida para imágenes fotográficas. Su principal ventaja radica en el alto ratio de compresión que se logra manteniendo una calidad aceptable. Además, la relación entre compresión y calidad puede ser ajustada para adaptarse a diferentes requerimientos. Fue desarrollado por el Joint Photographic Experts Group, un comité de expertos del ISO/CCITT, que lo lanzó en 1992. Este algoritmo de compresión utiliza dos "defectos" que el sistema visual humano posee para lograr eliminar información de la imagen que el ojo no es capaz de detectar. El primero de ellos consiste en que no tenemos la misma capacidad para apreciar las variaciones de crominancia que las variaciones de luminancia. La segunda, es que somos capaces de detectar ligeros cambios en el tono ent...

The U.S. Geological Survey (USGS) conducts baseline and storm response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms. On September 17, 2004, the USGS conducted an oblique aerial photographic survey from Crawfordville, Florida, to Petit Bois Island, Mississippi, aboard a Piper Navajo Chieftain aircraft at an altitude of 500 feet (ft) and approximately 1,200 ft offshore. This mission was flown to collect post-Hurricane Ivan data for assessing incremental changes in the beach and near shore since the last survey, flown in July 2001, and can be used in the assessment of future coastal change. The photographs provided here are Joint Photographic Experts Group (JPEG) images. GPS data are input into the EXIF header of the dig...
