2、andard ISO/IEC 15444-5:2003 (first edition, 2003-11-15) has been adopted withoutmodification (IDT) as CSA Standard CAN/CSA-ISO/IEC 15444-5:04, which has been approved as a NationalStandard of Canada by the Standards Council of Canada.ISBN 1-55397-747-3 December 2004The Canadian Standards Association
3、 (CSA), under whose auspices this National Standard has been produced, was chartered in 1919 and accredited by the Standards Council of Canada to the National Standards system in 1973. It is a not-for-profit, nonstatutory, voluntary membership association engaged in standards development and certifi
4、cation activities. CSA standards reflect a national consensus of producers and users including manufacturers, consumers, retailers, unions and professional organizations, and governmental agencies. The standards are used widely by industry and commerce and often adopted by municipal, provincial, and
5、 federal governments in their regulations, particularly in the fields of health, safety, building and construction, and the environment. Individuals, companies, and associations across Canada indicate their support for CSAs standards development by volunteering their time and skills to CSA Committee
6、 work and supporting the Associations objectives through sustaining memberships. The more than 7000 committee volunteers and the 2000 sustaining memberships together form CSAs total membership from which its Directors are chosen. Sustaining memberships represent a major source of income for CSAs sta
7、ndards development activities. The Association offers certification and testing services in support of and as an extension to its standards development activities. To ensure the integrity of its certification process, the Association regularly and continually audits and inspects products that bear t
8、he CSA Mark. In addition to its head office and laboratory complex in Toronto, CSA has regional branch offices in major centres across Canada and inspection and testing agencies in eight countries. Since 1919, the Association has developed the necessary expertise to meet its corporate mission: CSA i
9、s an independent service organization whose mission is to provide an open and effective forum for activities facilitating the exchange of goods and services through the use of standards, certification and related services to meet national and international needs.For further information on CSA servic

11、ement of voluntary standardization in the national interest. The principal objects of the Council are to foster and promote voluntary standardization as a means of advancing the national economy, benefiting the health, safety, and welfare of the public, assisting and protecting the consumer, facilit
12、ating domestic and international trade, and furthering international cooperation in the field of standards. A National Standard of Canada is a standard which has been approved by the Standards Council of Canada and one which reflects a reasonable agreement among the views of a number of capable indi
13、viduals whose collective interests provide to the greatest practicable extent a balance of representation of producers, users, consumers, and others with relevant interests, as may be appropriate to the subject in hand. It normally is a standard which is capable of making a significant and timely co
14、ntribution to the national interest. Approval of a standard as a National Standard of Canada indicates that a standard conforms to the criteria and procedures established by the Standards Council of Canada. Approval does not refer to the technical content of the standard; this remains the continuing
15、 responsibility of the accredited standards development organization. Those who have a need to apply standards are encouraged to use National Standards of Canada whenever practicable. These standards are subject to periodic review; therefore, users are cautioned to obtain the latest edition from the
16、 organization preparing the standard.The responsibility for approving National Standards of Canada rests with theStandards Council of Canada270 Albert Street, Suite 200Ottawa, Ontario, K1P 6N7CanadaAlthough the intended primary application of this Standard is stated in its Scope, it is importantto n

34、iv ISO/IEC 2003 All rights reserved Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of In
35、ternational Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liai
36、son with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint tech
37、nical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is
38、drawn to the possibility that some of the elements of this part of ISO/IEC 15444 may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 15444-5 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technolo
39、gy, Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information, in collaboration with ITU-T. The identical text is published as ITU-T Rec. T.804. ISO/IEC 15444 consists of the following parts, under the general title Information technology JPEG 2000 image coding system: Part
40、 1: Core coding system Part 2: Extensions Part 3: Motion JPEG 2000 Part 4: Conformance testing Part 5: Reference software Part 6: Compound image file format Part 9: Interactivity tools, APIs and protocols Part 12: ISO base media file format ISO/IEC 15444-5:2003 (E) ITU-T Rec.

41、NATIONAL STANDARD ITU-T RECOMMENDATION Information technology JPEG 2000 image coding system: Reference software 1 Scope ITU-T Rec. T.800 | ISO/IEC 15444-1 defines a set of lossless and lossy compression methods for coding continuous-tone, bi-level, greyscale or colour digital still images. This Reco
42、mmendation | International Standard provides two independently created software reference implementations of ITU-T Rec. T.800 | ISO/IEC 15444-1, in order to assist implementers of ITU-T Rec. T.800 | ISO/IEC 15444-1 in testing and understanding its content. The reference software is informative only.
43、 This Recommendation | International Standard does not define any additional part of the JPEG 2000 image coding system. Each version of the reference software contains source code, which may be compiled to provide the following functionality: transcoding from selected, widely available image formats
44、 into a JPEG 2000 codestream; transcoding from selected, widely available image formats into the JP2 file format; selection of a wide range of JPEG 2000 encoding options (as documented in each reference software); decoding from a JPEG 2000 codestream to a range of selected widely available image for
45、mats; partial processing of a JP2 file to extract a JPEG 2000 codestream for decoding to a range of selected widely available image formats; NOTE The reference software does not implement a conforming JP2 file reader. See clause 9. some additional tools to help with evaluation and testing. The refer
46、ence software is intended for use as a testing and validation tool for other implementations of JPEG 2000, and to help in the understanding of ITU-T Rec. T.800 | ISO/IEC 15444-1. Although components of the reference software may find application in software intended for product development, this was
47、 not an objective of the development of this software, and prospective implementors are cautioned against making any estimations of performance or resource usage based on the reference software. 2 Normative references The following Recommendations and International Standards contain provisions which
48、 through reference in this text, constitute provisions of the Recommendation | International Standard. At the time of publication, the editions indicated were valid. All Recommendations and Standards are subject to revision, and parties to agreements based on this Recommendation | International Sta
49、ndard are encouraged to investigate the possibility of applying the most recent edition of the Recommendations and Standards listed below. Members of IEC and ISO maintain registers of currently valid International Standards. The Telecommunication Standardization Bureau of the ITU maintains a list of currently valid ITU-T Recommendations. 2.1 Identical Recommendations | International Standards ITU-T Recommendation T.800 (2002) | ISO/IEC 15444-1:2002, Information technology JPEG 2000 I
