23、servedForewordISO (the International Organization for Standardization) and IEC (the International ElectrotechnicalCommission) form the specialized system for worldwide standardization. National bodies that aremembers of ISO or IEC participate in the development of International Standards through tec

24、hnicalcommittees 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 internationalorganizations, governmental and non-governmental, in liaison with ISO and IEC, also take part

25、 in thework.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IECJTC 1. Draft International Standards adopted by the joint technical committee

26、are circulated to nationalbodies for voting. Publication as an International Standard requires approval by at least 75 % of thenational bodies casting a vote.Attention is drawn to the possibility that some of the elements of this part of ISO/IEC 13249 may be thesubject of patent rights. ISO and IEC

27、shall not be held responsible for identifying any or all such patentrights.International Standard ISO/IEC 13249-5 was prepared by Joint Technical Committee ISO/IEC JTC 1,Information technology, Subcommittee SC 32, Data management and interchange.ISO/IEC 13249 consists of the following parts, under t

28、he general title Information technology Databaselanguages SQL multimedia and application packages: Part 1: Framework Part 2: Full-Text Part 3: Spatial Part 4: General purpose facilities Part 5: Still Image Part 6: Data MiningAnnexes A and B of this part of ISO/IEC 13249 are for information only.ISO/

29、IEC 13249-5:2001(E) ISO/IEC 2001 - All rights reserved Introduction viiIntroductionThe purpose of this International Standard is to define multimedia and application specific types and theirassociated routines using the user-defined features in ISO/IEC 9075.This document is based on the content of I

30、SO/IEC International Standard Database Language (SQL).The organization of this part of ISO/IEC 13249 is as follows:1) Clause 1, “Scope“, specifies the scope of this part of ISO/IEC 13249.2) Clause 2, “Normative references“, identifies additional standards that, through reference in this part ofISO/I

31、EC 13249, constitute provisions of this part of ISO/IEC 13249.3) Clause 3, “Definitions, notations, and conventions“, defines the notations and conventions used inthis part of ISO/IEC 13249.4) Clause 4, “Concepts“, presents concepts used in the definition of this part of ISO/IEC 13249.5) Clause 5, “

32、Still Image Types“, defines the still image user-defined types and associated routines.6) Clause 6, “Feature Types“, defines the user-defined types provided for the manipulation of still imagefeatures.7) Clause 7, “SQL/MM Still Image Information Schema“ defines the SQL/MM Still Image InformationSche

33、ma.8) Clause 8, “SQL/MM Still Image Definition Schema“ defines the SQL/MM Still Image DefinitionSchema.9) Clause 9, “Status Codes“, defines the SQLSTATE codes used in this part of ISO/IEC 13249.10) Clause 10, “Conformance“, defines the criteria for conformance to this part of ISO/IEC 13249.11) Annex

34、 A, “Implementation-defined elements“, is an informative Annex. It lists those features forwhich the body of this part of ISO/IEC 13249 states that the syntax or meaning or effect on thedatabase is partly or wholly implementation-defined, and describes the defining information that animplementor sha

35、ll provide in each case.12) Annex B, “Implementation-dependent elements“, is an informative Annex. It lists those features forwhich the body of this part of ISO/IEC 13249 states explicitly that the meaning or effect on thedatabase is implementation-dependent.In the text of this part of ISO/IEC 13249

36、, Clauses begin a new odd-numbered page, and in Clause 5, “StillImage Types“, through Clause 10, “Conformance“, Subclauses begin a new page. Any resulting blankspace is not significant.INTERNATIONAL STANDARD ISO/IEC 13249-5:2001(E) ISO/IEC 2001 - All rights reserved Scope 1Information technology Dat

38、this part of ISO/IEC 13249,d) defines concepts specific to this part of this part of ISO/IEC 13249,e) defines the still image user-defined types and their associated routines.The still image user-defined types defined in this part adhere to the following: A still image user-defined type is generic t

39、o image data handling. It addresses the need to store,manage and retrieve information based on aspects of image data such as height, width and formatand based on image features such as average color, color histogram, positional color and texture. A still image user-defined type does not redefine the

40、 database language SQL directly or incombination with another still image data type.The still image user-defined types are applicable to all different image formats. However, not all functionalitycanbeusedwithallknownstillimageformats.An implementation of this part of ISO/IEC 13249 may exist in envi

41、ronments that also support information andcontent management, decision support, data mining, and data warehousing systems.Application areas addressed by implementations of this part of ISO/IEC 13249 include, but are not restrictedto, graphics, multimedia, scientific research, and medicine.ISO/IEC 13
