| In 2010, after completion of the image coding specification, the ITU-T and ISO/IEC also published a motion format specification (ITU-T T.833 | ISO/IEC 29199-3), a conformance test set (ITU-T T.834 | ISO/IEC 29199-4), and reference software (ITU-T T.835 | ISO/IEC 29199-5) for JPEG XR. In 2011, they published a technical report describing the workflow architecture for the use of JPEG XR images in applications (ITU-T T.Sup2 | ISO/IEC TR 29199-1).
| |
| | |
| ==Description==
| |
| | |
| ===Capabilities===
| |
| | |
| JPEG XR is an image file format that offers several key improvements over [[JPEG]], including:<ref name="ms-billcrow-jpegxr">{{cite web|title=JPEG XR is Now an International Standard|url=http://blogs.msdn.com/billcrow/archive/2007/03.aspx|publisher=Microsoft Corporation|work=[[Microsoft Developer Network#Blogs|Microsoft Developer Network blogs]], Bill Crow's blog|last=Bill|first=Crow|date=30 July 2009|accessdate=24 October 2009}}</ref>
| |
| | |
| :;Better compression:
| |
| ::JPEG XR file format supports higher compression ratios in comparison to JPEG for encoding an image with equivalent quality.
| |
| | |
| :;Lossless compression:
| |
| ::JPEG XR also supports [[lossless compression]]. The signal processing steps in JPEG XR are the same for both lossless and lossy coding. This makes the lossless mode simple to support and enables the "trimming" of some bits from a lossless compressed image to produce a lossy compressed image.
| |
| | |
| :;Tile structure support:
| |
| ::A JPEG XR coded image can be segmented into ''tile'' regions. The data for each region can be decoded separately. This enables rapid access to parts of an image without needing to decode the entire image. When a type of tiling referred to as "soft tiling" is used, the tile region structuring can be changed without fully decoding the image and without introducing additional distortion.
| |
| | |
| :;Support for more color accuracy:
| |
| ::In image and graphics representations, the color associated with each point in the picture (called a [[pixel]]) is represented as a set of numbers. Each color can be expressed as a combination of numbers that each represent the intensity of one of the components of a color (known as the [[Channel (digital image)|channel]]) which consists of Red, Green and Blue (the three colors of light) ''color primary''. Such a color scheme is called the [[RGB color model]]. Using an alternative set of color primaries, graphic files may treat the color of each point as a combination of Cyan, Magenta, Yellow, and Black (the four ink colors of [[printer (computing)|printer]]s) and therefore store the color of each point in four channels. Such a color scheme is called the [[CMYK color model]]. When the image being stored contains only black, white and shades of gray as colors, the image may be represented using a single [[grayscale]] channel for each pixel that only represents the intensity of the gray shade.
| |
| | |
| ::JPEG supports [[List of monochrome and RGB palettes#24-bit RGB|24-Bit RGB]] (also known as [[True Color|truecolor]]): This representation stores each channel as an 8-bit number, ''an integer number from 0 to 255''. In this case, the greater the number, the more intense the color component is. For instance, 25 in red channel represents dark red while 255 indicates fully vibrant red. This enables more than 16 million color possibilities. JPEG also supports 8-bit [[grayscale]] scheme, so that each pixel can have one of 256 possible shades of gray.
| |
| | |
| ::Also supported is [[List of monochrome and RGB palettes#15-bit RGB|15-Bit and 16-Bit RGB]] (also known as [[Highcolor]]), along with [[List of monochrome and RGB palettes#30-bit RGB|30-Bit RGB]]. {{Citation needed|reason=This claim needs a reliable source; I am very surprised to learn that JPEG supports 30-bit (i.e., 10 bits per channel). In particular, there is no evidence of this on the JPEG page.|date=March 2013}}
| |
| | |
| ::JPEG XR adds supports for [[List of monochrome and RGB palettes#48-bit RGB|48-bit integer RGB]] (also known as [[deep color]]): This representation stores the values of each of the three channels as a 16-bit number, ''an integer number from 0 to 65,535'', where 0 denotes least intensity and 65535 the greatest. Therefore, each channel stores a much finer grade of intensity.
| |
| | |
| ::JPEG XR also supports 16-bit per component (64-bit per pixel) integer [[CMYK color model]].<ref name="ms-billcrow-pixelformat1">{{cite web|url=http://blogs.msdn.com/billcrow/archive/2006/06/19/636858.aspx|title=Pixel Formats (Part 1: Unsigned Integers)|last=Crow|first=Bill|work=Bill Crow's Digital Imaging & Photography Blog|publisher=Microsoft Developer Network|date=1 June 2006|accessdate=26 October 2009}}</ref>
| |
| | |
| ::16-bit and 32-bit fixed point color component codings are also supported in JPEG XR. In such encodings, the most-significant 4 bits of each color channel are treated as providing additional "headroom" and "toe room" beyond the range of values that represents the nominal black-to-white signal range.
| |
| | |
| ::Moreover, 16-bit and 32-bit floating point color component codings are also supported in JPEG XR. In these cases the image is interpreted as floating point data, although the JPEG XR encoding and decoding steps are all performed using only integer operations (to simplify the compression processing).
| |
| | |
| ::The shared-exponent floating point color format known as [[RGBE image format|RGBE]] ([[Radiance (software)|Radiance]]) is also supported, enabling more faithful storage of [[High dynamic range imaging|High Dynamic Range (HDR) images]].
| |
| | |
| ::In addition to RGB and CMYK formats, JPEG XR also supports [[grayscale]] and multi-[[Channel (digital image)|channel]] color encodings with an arbitrary number of channels.
| |
| | |
| ::The color representations, in most cases, are transformed to an internal color representation. The transformation is entirely reversible, so that this color transformation step does not introduce distortion and lossless coding modes can be supported.
| |
| | |
| :;Transparency map support:
| |
| ::An [[Alpha compositing|alpha channel]] may be present to represent transparency, so that alpha blending overlay capability is enabled.
| |
| | |
| :;Compressed-domain image modification:
| |
| ::In JPEG XR, full decoding of the image is unnecessary for converting an image from a lossless to lossy encoding, reducing the fidelity of a lossy encoding, or reducing the encoded image resolution.
| |
| | |
| ::Full decoding is also unnecessary for certain editing operations such as cropping, horizontal or vertical flips, or [[Cardinal direction|cardinal]] rotations.
| |
| | |
| ::The tile structure for access to image regions can also be changed without full decoding and without introducing distortion.
| |
| | |
| :;Metadata support:
| |
| ::A JPEG XR image file may optionally contain an embedded [[International Color Consortium|ICC]] color profile, to achieve consistent color representation across multiple devices.
| |
| | |
| ::[[Exif]] and [[Extensible Metadata Platform|XMP]] metadata formats are also supported.
| |
| | |
| ===Container format===
| |
| One file [[container format (digital)|container format]] that can be used to store JPEG XR image data is specified in Annex A of the JPEG XR standard. It is a [[TIFF]]-like format using a table of ''[[Image File Directory]]'' (IFD) tags. A JPEG XR file contains image data, optional alpha channel data, metadata, optional [[Extensible Metadata Platform|XMP]] metadata stored as [[Resource Description Framework|RDF/XML]], and optional [[Exif]] metadata, in IFD tags. The image data is a contiguous self-contained chunk of data. The optional alpha channel, if present, can be compressed as a separate image record, enabling decoding of the image data independently of transparency data in applications which do not support transparency. (Alternatively, JPEG XR also supports an "interleaved" alpha channel format in which the alpha channel data is encoded together with the other image data in a single compressed codestream.)
| |
| | |
| Being TIFF-based, this format inherits all of the limitations of the TIFF format including the 4 GB file-size limit.
| |
| | |
| New work has been started in the JPEG committee to enable the use of JPEG XR image coding within the JPX file storage format — enabling use of the JPIP protocol, which allows interactive browsing of networked images.<ref name="July09PR"/> Additionally, a Motion JPEG XR specification was approved as an ISO standard for motion (video) compression in March 2010.<ref>{{cite web|url=http://www.jpeg.org/newsrel28.html|title=JPEG launches Innovations group, new book " JPEG 2000 Suite " published |publisher=jpeg.org|date=19 March 2010}}</ref>

| [[File:Comparison between JPEG, JPEG 2000 and JPEG XR.png|thumb|right|350px|Comparison between JPEG 2000, JPEG XR, and JPEG.]]
| |
| JPEG XR's design<ref name="T832"/><ref name="SPIEoverview">S. Srinivasan, C. Tu, S. L. Regunathan, and G. J. Sullivan, “[http://spie.org/x648.html?product_id=767840 HD Photo: A New Image Coding Technology for Digital Photography]”, ''SPIE Applications of Digital Image Processing XXX'', [[SPIE]] Proceedings, volume 6696, paper 66960A, September 2007.</ref> is conceptually very similar to [[JPEG]]: the source image is optionally converted to a [[luma (video)|luma-chroma]] colorspace, the chroma planes are optionally [[chroma subsampling|subsampled]], each plane is divided into fixed-size blocks, the blocks are transformed into the frequency domain, and the frequency coefficients are quantized and [[entropy encoding|entropy coded]]. Major differences include the following:
| |
| | |
| * JPEG supports bit depths of 8 and 12 bits; JPEG XR supports bit depths of up to 32 bits. JPEG XR also supports lossless and lossy compression of floating-point image data (by representing the floating-point values in an [[IEEE 754]]-like format, and encoding them as though they were integers) and [[RGBE image format|RGBE]] imagery.
| |
| | |
| * [[JFIF]] and other typical image encoding practices specify a linear transformation from RGB to [[YCbCr]], which is slightly lossy in practice because of [[roundoff error]]. JPEG XR specifies a lossless colorspace transformation, given (for RGB) by
| |
| ::<math>V = B - R\,</math>
| |
| ::<math>U = G - R - \left\lceil \frac{V}{2} \right\rceil</math>
| |
| ::<math>Y = G - \left\lceil \frac{U}{2} \right\rceil</math>
| |
| | |
| * While JPEG uses 8 × 8 blocks for its frequency transformation, JPEG XR primarily uses 4 × 4 block transforms. (2 × 4 and 2 × 2 transformations are also defined for special cases involving [[chroma subsampling]].)
| |
| | |
| * While JPEG uses a single transformation stage, JPEG XR applies its 4 × 4 core transform in a two-level hierarchical fashion within 16 × 16 ''macroblock'' regions. This gives the transform a [[wavelet]]-like multi-resolution hierarchy and improves its compression capability.
| |
| | |
| * The [[Discrete cosine transform|DCT]], the frequency transformation used by JPEG, is slightly lossy because of roundoff error. JPEG XR uses a type of integer transform employing a [[lifting scheme]], which resembles a 4 × 4 DCT but is lossless (exactly invertible).
| |
| | |
| * JPEG XR allows an optional overlap prefiltering step before each of its 4 × 4 core transform stages. The filter operates on 4 × 4 blocks which are offset by 2 samples in each direction from the 4 × 4 core transform blocks. Its purpose is to improve compression capability and reduce [[compression artifact|block-boundary artifacts]] at low bitrates. At high bitrates, where such artifacts are typically not a problem, the prefiltering can be omitted to reduce encoding and decoding time. The overlap filtering is constructed using integer operations following a [[lifting scheme]], so that it is also lossless.
| |
| | |
| * In JPEG, the image DC coefficients of the DCT are predicted by applying DC prediction from the left neighbor transform block, and no other coeffients are predicted. In JPEG XR, blocks are grouped into macroblocks of 16 × 16 samples, and the DC coefficients from each macroblock are passed through another level of frequency transformation, leaving three types of coefficients to be entropy coded: the macroblock DC coefficients (called DC), macroblock-level AC coefficients (called "lowpass"), and lower-level AC coefficients (called AC). Prediction of coefficient values across transform blocks is applied to the DC coefficients and to an additional row or column of AC coefficients as well.
| |
| | |
| * JPEG XR supports the encoding of an image by decomposing it into smaller individual rectangular ''tile'' area regions. Each tile area can be decoded independently from the other areas of the picture. This allows fast access to spatial areas of pictures without decoding the entire picture.
| |
| | |
| * JPEG XR's entropy coding phase is more adaptive and complex than JPEG's, involving a DC and AC coefficient prediction scheme, adaptive coefficient reordering (in contrast to JPEG's fixed zigzag ordering), and a form of adaptive Huffman coding for the coefficients themselves.
| |
| | |
| * JPEG uses a single quantization step size per DC/AC component per color plane per image. JPEG XR allows a selection of DC quantization step sizes on a ''tile'' region basis, and allows lowpass and AC quantization step sizes to vary from macroblock to macroblock.
| |
| | |
| * Because all encoding phases except quantization are lossless, JPEG XR is lossless when all quantization coefficients are equal to 1. This is not true of JPEG. JPEG defines a separate lossless mode which does not use the DCT, but it is not implemented by [[libjpeg]] and therefore not widely supported.
| |
| | |
| The HD Photo bitstream specification claims that "HD Photo offers image quality comparable to [[JPEG-2000]] with computational and memory performance more closely comparable to JPEG", that it "delivers a lossy compressed image of better perceptive quality than JPEG at less than half the file size", and that "lossless compressed images … are typically 2.5 times smaller than the original uncompressed data".

| Microsoft has patents on the technology in JPEG XR. A Microsoft representative stated in a January 2007 interview that in order to encourage the adoption and use of HD Photo, the specification is made available under the [[Microsoft Open Specification Promise]], which asserts that Microsoft allows implementation of the specification for free, and will not file suits on the patented technology for its implementation,<ref>{{cite web|url=http://news.com.com/2100-1045_3-6153730.html
