Press Release For immediate release

JPEG launches Innovations group, new book JPEG 2000 Suite published

The Joint Photographic Experts Group (JPEG) is a Working Group of ISO/IEC, the International Organisation for Standardization / International Electrotechnical Commission, (ISO/IEC JTC 1/SC 29/WG 1) and of the International Telecommunication Union (ITU-T SG16), responsible for the popular JPEG, JPEG 2000 and more recently, the JPSearch, JPEG XR families of imaging standards. The WG1 group meets nominally three times a year, in Europe, North America and Asia. The latest meeting was held on March 15 - 19, 2010, at Franklin W. Olin College of Engineering, Needham, Massachusetts, USA, hosted by the United States National Body.

JPEG is pleased to announce the formation its Innovations group. JPEG Innovations is chartered to increase awareness of JPEG family of standards, to identify, explore and investigate new image related standard topics, to engage with industry and academia to hold workshops and seminars on these areas and raise the momentum for starting new standardization work items. All interested parties are invited to collaborate with JPEG Innovations by contacting the chair, Dr. Touradj Ebrahimi at innovations@jpeg.org.

The Digital Cinema (DC) ad hoc group continued its work on additional frame-rates for Digital Cinema and Archival applications. The amendment on guidelines for Digital Cinema was updated. This amendment enables the determination of the data size of the compressed bit stream from the predefined bit rate and allows a wider range of frame rates. The broadcast application sub-group has progressed on the new broadcast profiles. Comments and requirements are welcome and can be sent to JPEG Committee.

In JPEG XR, JPEG is pleased to announce that it has completed its work on all four parts of the JPEG XR image coding system at this meeting, with the particular milestones as noted below:

The Part 1 system architecture technical report (ISO/IEC TR 29199-1) has been approved to proceed to final technical report. This technical report will provide valuable information to aid in the effective deployment of a variety of products that support the JPEG XR standard.

  • A new edition of the Part 2 image coding specification (ITU-T Rec. T.832 and ISO/IEC 29199-2) has been prepared for publication, which resolves the identified needs for correction and clarification of the coding specification text.
  • The Part 3 Motion JPEG XR specification (ISO/IEC 29199-3) has been finalized, enabling the use of JPEG XR encoding for motion (video) compression. This new standard, ISO/IEC 29199-3 Motion JPEG XR, specifies how JPEG XR may be stored in the family of file formats based on the ISO Base Media File Format. This parallels the use of the classic JPEG codec for "Motion JPEG" and the use of the JPEG 2000 codec for Motion JPEG 2000 (ITU-T Rec. T.802 and ISO/IEC 15444-3). This support is suitable for use when interframe coding is not needed or desirable, or when the JPEG XR codec is already available (for example, in a still camera using JPEG XR that can also shoot motion sequences). In the file format, the logically repeated codec configuration information is stored once, both compacting the file and reducing the number of times a decoder must be initialized.
  • The Part 4 conformance testing specification is now available to the public as a prepublication of the approved ITU-T Rec. T.834 (available at http://www.itu.int/rec/TREC- T.834). It will soon be published by ISO/IEC as 29199-4.
  • The Part 5 reference software specification is now available to the public as a prepublication of the approved ITU-T Rec. T.835 (available at http://www.itu.int/rec/T-REC-T.835). It will soon be published by ISO/IEC as 29199-5.

In ISO/IEC 24800 JPSearch, the committee produced the Final Draft International Standards for Part 2, Registration, identification, and management of schema and ontology, and Part 4, File format for metadata embedded in image data. Final Committee Draft for JPSearch Part 5, Data interchange format between image repositories, is also produced at this meeting. JPSearch enables standardized framework for search, retrieval, and exchange of images with or without accompanying metadata. Part 2 provides standardized metadata schema (JPSearch Core Metadata) and supports minimal interoperability among systems with heterogeneous metadata format. In this meeting, discussion on the benchmark description for JPSearch framework has started and a draft call for requirements was issued. All interest parties in benchmarking image retrieval systems are invited to submit requirements of benchmark description framework with relevant usage scenarios.

The Advanced Image Coding and Evaluation Methodologies (ISO/IEC 29170 - AIC), is a new work item for standardization of a new evaluation approaches and image compression system for any potential technologies can be identified which significantly would improve the current image coding standards. AIC ad hoc group is pleased to announce the production of calls for technologies, use cases, requirement, evaluation procedures and test material for three targeted applications: medical imaging, camera sensors imaging and security applications. AIC ad hoc group also continues the progress in the creation of guidelines for evaluation of coding technologies.

The JPEG committee welcomes a new book, The JPEG 2000 Suite, that has been published by Wiley and edited by Peter Schelkens, Athanassios Skodras and Touradj Ebrahimi. The book provides an excellent overview of the different parts of the JPEG 2000 standard and the applications covered. The book is based on contributions of JPEG committee members involved in the JPEG 2000 standardization process.

"JPEG looks forward to broad participations in JPEG Innovations, JPEG welcomes the publications of a new book, The JPEG 2000 Suite, authored by experts from the committee," said Dr. Daniel Lee of eBay Inc., Convener of the JPEG committee.

The JPEG web site (http://www.jpeg.org) has sponsorship opportunities for all companies involved in developments around JPEG. The marketing departments of interested companies should contact the webmaster, Richard Clark (webmaster@jpeg.org), for this high-traffic site.

The next WG 1 Meeting (52nd) will be held in Brussels, Belgium, hosted by the Belgium National Body, July 12 - 16, 2010.
