Editing JPEG 2000 (section)

==Design goals==
While there is a modest increase in compression performance of JPEG&nbsp;2000 compared to JPEG, the main advantage offered by JPEG&nbsp;2000 is the significant flexibility of the codestream. The codestream obtained after compression of an image with JPEG&nbsp;2000 is scalable in nature, meaning that it can be decoded in a number of ways; for instance, by truncating the codestream at any point, one may obtain a representation of the image at a lower resolution, or [[signal-to-noise ratio]] – see [[Lossy data compression#Downsampling/compressed representation scalability|scalable compression]]. By ordering the codestream in various ways, applications can achieve significant performance increases. However, as a consequence of this flexibility, JPEG&nbsp;2000 requires [[codec]]s that are complex and computationally demanding. Another difference, in comparison with JPEG, is in terms of visual [[compression artifact|artifacts]]: JPEG&nbsp;2000 only produces [[ringing artifacts]], manifested as blur and rings near edges in the image, while JPEG produces both ringing artifacts and 'blocking' artifacts, due to its [[JPEG#Block splitting|8×8 blocks]].

JPEG 2000 has been published as an [[International Organization for Standardization|ISO]] standard, ISO/IEC 15444. The cost of obtaining all documents for the standard has been estimated at 2,718{{nbsp}}[[Swiss franc|CHF]] ([[United States dollar|US$]]2,720 as of 2015).<ref>{{cite journal |url=http://www.diva-portal.org/smash/get/diva2:925474/FULLTEXT01.pdf |last1=Lundell |first1=B. |last2=Gamalielsson |first2=J. |last3=Katz |first3=A. |date=2015 |title=On Implementation of Open Standards in Software: To What Extent Can ISO Standards Be Implemented in Open Source Software? |journal=International Journal of Standardization Research |volume=13 |issue=1 |pages=47–73 |doi=10.4018/IJSR.2015010103 }}</ref>

===Applications===
Notable markets and applications intended to be served by the standard include:
* Consumer applications such as multimedia devices (e.g. digital cameras, personal digital assistants, 3G mobile phones, color facsimile, printers, scanners)
* Client/server communication (e.g. the Internet, image database, video streaming, video server)
* Military/surveillance (e.g. HD satellite images, Motion detection, network distribution and storage)
* [[Medical imagery]], specifically the [[DICOM]] specifications for medical data interchange.
* Biometrics
* [[Remote sensing]]
* High-quality frame-based video recording, editing and storage.
* Live HDTV feed contribution (I-frame only video compression with low transmission latency), such as live HDTV feed of a sport event linked to the TV station studio
* [[Digital cinema]], such as [[Digital Cinema Package]]
* Digitized Audio-visual contents and images for long term [[digital preservation]]
* [[World Meteorological Organization]] has built JPEG 2000 Compression into the new GRIB2 file format.  The GRIB file structure is designed for global distribution of meteorological data.  The implementation of JPEG 2000 compression in GRIB2 has reduced file sizes up to 80%.<ref>[http://www.cpc.ncep.noaa.gov/products/wesley/wgrib2/ wgrib2 home page]</ref>
