Jpeg, английский
- A graphics format capable of representing up to 16.7 million colours that is ideal for complex pictures of natural, realworld scenes, including photographs, realistic artwork, and paintings. jpeg stands for joint photographic experts group.
- Расширение стандарта jpeg, в котором различные части изображения могут сжиматься по-разному. например, фон может быть сжат более сильно, т.к. он не столь чувствителен к потере качества, а объекты на переднем плане сжаты менее сильно
- Cтандарт сжатия графических файлов, часто используемый для представления больших картинок в www
- Jpeg is a standard for the encoding and compression of images. jpeg is used in the video surveillance systems to compress and store individual frames of video. jpeg was developed by the joint photographic experts group.
- Joint photographic experts group. a group that has recommended a compression
- Joint photographic experts group: the name of the committee that created a standard for encoding still images.
- Joint photographic experts group
- A format designed by the joint photographic experts group, that allows files of coloured images to be compressed to a smaller digital file than if the full range of colours were to be saved. also .jpg as a computer file extension.
- Joint photographic experts group. a group that has recommended a compression algorithm for still digital images that can compress with ratios of over 10:1. also the name of the format itself. 21 / 43 k
- Joint photographic experts group. this is the name of the committee that designed the standard image compression algorithm. jpeg was designed for compressing full colour or grey scale digital images of natural scenes. it doesn’t work so well with non-realistic images, such as cartoons however. jpeg does not handle the compression of black and white (1 bit-per-pixel) images or moving pictures.

- Формат сжатия цифровых изображений более чем 10:1.

- The de facto standard for image compression in digital imaging devices. jpeg is a “lossy” compression format, capable of reducing a digital image file to about 5% of its normal size. the resulting decompression of the file can cause "blockiness," "jaggies," or "pixelization" in certain digital images. the greater the compression levels, the more of a chance pixelization or "blockiness" will occur. the greater the pixel count, the less of a chance pixelization will occur.
Jpeg (the joint photographic experts group), английский
Was formed to create a standard for color and gray scale image compression. jpeg describes a variety of algorithms (rules), each of which is targeted for a specific type of image application. jpeg is the default format for most digital cameras. jpeg 2000 is the latest version. compressing a jpeg file, that is already compressed, will affect quality adversely.

Jpeg is an industry standard for stillimage compression that is moving into full-motion video. storing the video signal is a problem as it takes a 300 megabyte hard disk to store just 10 seconds of digital video. compression is the answer to storage problems. jpeg is a compression technique based upon intraframe encoding technology. it allows full restoration of symmetrically compressed images. symmetrical compression means that the image takes an equally long time to be compressed as it does to be decompressed. an asymmetrical scheme takes longer to compress an image than to decompress it and typically compresses the image on a computer other than the one to be used for decompression. relying on a newly adopted format to encode and decode digital images based on independent, nontemporal (intraframe) data, jpeg typically divides an image into 8 by 8 pixel blocks. these 64 square pixel matrices, called a search range, enable the aggregate quantization of the image and color data store by the pixels within each of the blocks. advanced jpeg algorithms that use larger search ranges, up to as much as 32 by 32 pixels, called super blocks, enable significantly faster encoding and decoding (up to 40 to 1 compression at about 4mb per second) but demand exponentially more processing power to maintain the same degree of image quality as the smaller pixel block. originally, jpeg was intended to compress only still images. however, video is nothing more than a quick presentation of successive still images. thus, a form of jpeg, known glossary/47 commonly as motion jpeg, is being used to compress motion images, particularly in applications like video editing where it is necessary to access individual frames of video and to scrub forward and backwards through source material. jpeg, mpeg and px64 specifications use a discrete cosine transform (dct), an encoding algorithm that quantifies the human eye`s ability to detect color and image distortion. dct parses color content data thereby enabling the use of a higher pixel depth sampling rate (typically 24 or 32 bits) than non-dct compression techniques. jpeg typically controls 24 bits per rgb pixel, retaining a high quantization of luminance and color resolution.

Jpeg joint photographic experts group the name of the committee that designed the standard image compression algorithm. jpeg is designed for compressing either full-color or grey-scale digital images of natural, real-world scenes. it does not work so well on non-realistic images, such as cartoons or line drawings. jpeg does not handle compression of black-and-white (1 bit-per-pixel) images or moving pictures. see jpg below. jpeg2000 the new jpeg compression standard that will be used in digital cameras and software starting in 2002 (maybe?). it will feature higher compression but with less image quality loss.

Jpeg rotate, английский
An expression media feature that enables the user to perform lossless jpeg image rotations of 90, -90 and 180 degrees.
Jpeg rotation, английский
A method of changing the orientation of a jpeg image by rotating it by varying degrees. rotation can be either lossy or lossless, depending upon your choice of rotation.
Jpeg system highlights, английский
Used to encode still images. it compresses about 20 to 1 ratio before visible image degradation occurs. compression ratios exceeding 100 to 1 attainable but image degrades excessively. at very low compression ratios of 5 to 1 maximum jpeg maintains absolute resolution. it excludes audio compression. symmetrical (compresses at same rate as it decompresses,) uses the same hardware to encode and decode. it compresses redundant data occurring within each frame (intraframe). compresses comparatively slow, depending on computer speed, about 1 to 3 seconds for a 1 mbyte image. decompresses a full sized image in .5 to 1 second or reduced sized image in real time. it has good quality at maximum compression.
