30、pecialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees, established by the respective organization, to deal with particular fields of technical activity. ISO and IEC techni
31、cal committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of international technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC1. Dr
32、aft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least75% of the national bodies casting a vote. International Standard ISO/IEC12087-3 was prepared by the Joint Technica
33、l Committee ISO/IEC JTC1, Information technology. ISO/IEC12087 initially consists of three parts, under the general title Information technology Computer graphics and image processing Image Processing and Interchange (IPI) Functional specification: Part1: Common architecture for imaging; Part2: Prog
34、rammers imaging kernel system application program interface; Part3: Image Interchange Facility (IIF). Annex A forms an integral part of this part of ISO/IEC12087. Annex B to Annex G are for information only.vi blankISO/IEC12087-3:1995(E) BSI 03-2000 1 Introduction ISO/IEC12087-1 establishes the conc
35、eptual and architectural framework for ISO/IEC12087. In particular, it defines the types of all image data objects, image-related data objects, and attributes that may be interchanged by means of the IPI-IIF. ISO/IEC12087-2 establishes the specification of the Programmers Imaging Kernel System (IPI-
36、PIKS). ISO/IEC12087-3 provides a data format specification and an application program interface specification. The IIF data format may be used for image data interchange in open, heterogeneous environments. It may also serve as a local file format for imaging applications, especially in conjunction
37、with ISO/IEC12087-2. In future, the IIF data format could be used by telecommunication standards. Examples are future versions of File Transfer, Access, and Management (FTAM), ISO/IEC8571; the Message Oriented Text Interchange Systems (MOTIS), ISO/IEC10021 (also known as Message Handling System (MHS
38、), CCITT Recommendation X.400). Thus the IIF data format could become part of application-oriented OSI communications protocols. Within the IIF data format (IIF-DF), compressed images may be specified and interchanged. For this purpose, the following standards are referenced: CCITT Recs. T.4 and T.6
39、 (Facsimile) ISO/IEC11544 (JBIG) ISO/IEC10918 (JPEG) ISO/IEC11172 (MPEG-1) Image data streams that conform to the encoded representation of compressed image data specified by these standards may be included in the IIF-DF. For instance, a time series image can be represented as an array of time slice
40、s, each of which is encoded according to the JPEG Standard. Furthermore, the IIF-DF allows images to be represented through the combination of compressed parts with uncompressed parts. It is also possible to use multiple compression methods within a single IIF-DF-conformant image. For instance, a co
41、lour image can be represented as tiled images whereby some tiles are encoded according to the lossy mode of the JPEG Standard and others according to the lossless mode. For detailed information concerning compressed data streams and compression/decompression functionality, refer to5.3.3 and7.1.6, re
42、spectively. There are various possibilities for interaction and data exchange between the IPI-PIKS domain and the IPI-IIF domain. Both domains are controlled by the application via application program interfaces (APIs). For a detailed description of the interworking between the IPI-PIKS and the IPI-
43、IIF refer to clause4 (theIPI-IIF architecture) and clause7 (the IPI-IIF Gateway functionality). For a description of the relation between the types of objects that may be interchanged by means of the IPI-IIF and those types of objects that may be processed by the IPI-PIKS, refer to clause6 (the prof
44、iles for the IIF data format). Refer also to ISO/IEC12087-1. 1 Scope This part of ISO/IEC12087 facilitates the interchange of digital images. For this purpose, conceptual, architectural, and functional definitions of the Image Interchange Facility (IPI-IIF) are established. ISO/IEC12087-3 consists o
45、f two major parts, the: a) IIF data format (IIF-DF) definition by means of a formal syntax, described according to the Abstract Syntax Notation One (ASN.1) refer to clause5, and the b) IIF Gateway definition by means of a manual page description of the functionality of an Application Program Interfa
46、ce (API) refer to clause7. An IPI-IIF-conformant implementation has to fulfill the functionality specification of the IIF Gateway, as outlined in clause7. Besides the IIF Gateway, there may be information processing systems (softwaresuch as parsers, generators, etc.) which read and/or write the IIF-
47、DF. The IPI-IIF is based on the definitions described in ISO/IEC12087-1, the “Common Architecture for Imaging”. The IPI-IIF, as a whole, may be characterized briefly as follows: c) By means of the IIF data format and Gateway, image data objects and image-related data objects are transported to and f
48、rom application environments.ISO/IEC12087-3:1995(E) 2 BSI 03-2000 d) By means of the full PIKS profile of the IPI-IIF data format (i.e.,a format for data interchange between IPI-IIF and IPI-PIKS), image data objects and image-related data objects are imported to and exported from the Programmers Ima
49、ging Kernel System (IPI-PIKS), defined in ISO/IEC12087-2. e) The IPI-IIF facilitates the storage of image data objects and image-related data objects in a variety of pre-defined storage modalities, including different periodicity organizations, such as pixel-interleaving or band-interleaving. f) This part of ISO/IEC12087 defines syntax of image data (and image-related data) streams. The encoding of IIF data types is defi
