Editing JPEG 2000 (section)

==Related standards==
Several additional parts of the JPEG 2000 standard exist; amongst them are ISO/IEC 15444-2:2000, JPEG&nbsp;2000 extensions defining the '''.jpx''' file format, featuring for example [[Trellis quantization]], an extended file format and additional [[color space]]s,<ref name="ISO-15444-2">{{cite web

Extensions for secure image transfer, ''JPSEC'' (ISO/IEC 15444-8), enhanced error-correction schemes for wireless applications, ''JPWL'' (ISO/IEC 15444-11) and extensions for encoding of volumetric images, ''JP3D'' (ISO/IEC 15444-10) are also already available from the ISO.

===JPIP protocol for streaming JPEG 2000 images===
In 2005, a JPEG 2000–based image browsing protocol, called [[JPIP]] was published as ISO/IEC 15444-9.<ref name="ISO-15444-9">{{cite web

JPEG 2000 data may also be streamed using the ECWP and ECWPS protocols found within the ERDAS [[ECW (file format)|ECW]]/JP2 SDK.

===Motion JPEG 2000===
{{main|Motion JPEG 2000}}
[[Motion JPEG 2000]], (MJ2), originally defined in Part 3 of the ISO Standard for JPEG2000 (ISO/IEC 15444-3:2002,) as a standalone document, has now been expressed by ISO/IEC 15444-3:2002/Amd 2:2003 in terms of the ISO Base format, ISO/IEC 15444-12 and in [[ITU-T]] Recommendation T.802.<ref>{{cite web | url=http://www.itu.int/rec/T-REC-T.802/en | title=T.802 : Information technology – JPEG 2000 image coding system: Motion JPEG 2000 | date=January 2005 | access-date=2009-11-01}}</ref> It specifies the use of the JPEG 2000 format for timed sequences of images (motion sequences), possibly combined with audio, and composed into an overall presentation.<ref name="ISO-15444-3">{{cite web

Filename extensions for Motion JPEG&nbsp;2000 video files are '''.mj2''' and '''.mjp2''' according to RFC 3745.

It is an open [[International Organization for Standardization|ISO]] standard and an advanced update to [[MJPEG]] (or MJ), which was based on the legacy [[JPEG]] format. Unlike common video formats, such as [[MPEG-4 Part 2]], [[Windows Media Video|WMV]], and [[H.264/MPEG-4 AVC|H.264]], MJ2 does not employ temporal or inter-frame compression. Instead, each frame is an independent entity encoded by either a lossy or lossless variant of JPEG&nbsp;2000. Its physical structure does not depend on time ordering, but it does employ a separate profile to complement the data. For audio, it supports [[LPCM]] encoding, as well as various MPEG-4 variants, as "raw" or complement data.<ref>{{Cite web|url=http://www.jpeg.org/jpeg2000/j2kpart3.html|archive-url=https://web.archive.org/web/20121005163250/http://jpeg.org/jpeg2000/j2kpart3.html|url-status=dead|title=Motion JPEG 2000 (Part 3)|archive-date=October 5, 2012}}</ref>

Motion JPEG 2000 (often referenced as MJ2 or MJP2) is considered as a digital archival format<ref>[https://www.loc.gov/preservation/digital/formats/fdd/fdd000127.shtml Motion JPEG 2000 mj2 File Format]. Sustainability of Digital Formats Planning for Library of Congress Collections.</ref> by the [[Library of Congress]] though MXF_OP1a_JP2_LL (lossless JPEG&nbsp;2000 wrapped in MXF operational pattern 1a) is preferred by the LOC Packard Campus for Audio-Visual Conservation.

===ISO base media file format===
ISO/IEC 15444-12 is identical with ISO/IEC 14496-12 (MPEG-4 Part 12) and it defines [[ISO base media file format]]. For example, Motion JPEG&nbsp;2000 file format, [[MP4]] file format or [[3GP]] file format are also based on this ISO base media file format.<ref name="mpeg4part12">{{cite web

===GML JP2 georeferencing===
The [[Open Geospatial Consortium]] (OGC) has defined a [[metadata (computing)|metadata]] standard for [[georeferencing]] JPEG&nbsp;2000 images with embedded [[XML]] using the [[Geography Markup Language]] (GML) format: ''GML in JPEG&nbsp;2000 for Geographic Imagery Encoding (GMLJP2)'', version 1.0.0, dated 2006-01-18.<ref name="gmljp2">Open Geospatial Consortium [http://www.opengeospatial.org/standards/gmljp2 GMLJP2 Home Page]</ref>  Version 2.0, entitled ''GML in JPEG 2000 (GMLJP2) Encoding Standard Part 1: Core'' was approved 2014-06-30.<ref name="gmljp2"/>

JP2 and JPX files containing GMLJP2 markup can be located and displayed in the correct position on the Earth's surface by a suitable [[Geographic Information System]] (GIS), in a similar way to [[GeoTIFF]] and GTG images.
