JPEG 2000 for Image Archiving, with a Discussion of Other Popular Image Formats Instructor: Robert Buckley, Xerox Corporation Monday May 21, 2007, 8:00 am – 12:00 noon Product Code: T1A | ||||||||||||||||||
|
This tutorial will begin with an introduction to commonly used digital image formats and image compression methods. This will lay the groundwork for discussing and comparing the two major formats for image archiving—TIFF and JPEG 2000—followed by a detailed explanation of the features and capabilities of JPEG 2000. TIFF is typically used to store uncompressed images; JPEG 2000 is a state-of-the-art standard for image compression. JPEG 2000 is attractive for image archiving and access because it can handle a wide range of applications, including gigabyte and high-dynamic range images, spectral imaging, digital cinema, and on-line image collections. This tutorial will explain key parts of the JPEG 2000 standard, demonstrate its capabilities, and discuss who’s using it and why.
Benefits:
Intended Audience: People in the archive, library, and museum communities who work with digital images and image collections who want to understand the tradeoffs between different image formats, what JPEG 2000 has to offer, and how their archiving application may benefit from it. Robert Buckley, research fellow with the Xerox Innovation Group in Webster, NY, is the Xerox representative on the US JPEG 2000 committee and was project editor for Part 6 of the JPEG 2000 standard, which defines the JPEG 2000 file format for compound and document images. Buckley was also the lead author for TIFF-FX, the IETF standard file format for Internet fax. He currently chairs the CIE Technical Committee on Archival Color Imaging. Buckley has given several invited talks on JPEG 2000 to the cultural heritage community and has consulted on its use in archiving applications.

Using JHOVE for Format Identification, Validation, and Characterization Instructor: Steve Abrams, Harvard University Library Monday May 21, 2007, 1:15 pm – 3:15 pm Product Code: T1B | ||||||||||||||||||
|
Proper characterization ofmanaged digital assets is a fundamental requirement of an archival systemif it is tomaintain the usability of those assets over time. Perhaps no characterization property is as important as format, which provides the basis for the correct interpretation and rendering of otherwise opaque bit streams. The format-related use cases of primary importance are identification, validation, and haracterization, which in turn facilitate assessment and intervention to mitigate the risk of information loss. This tutorial will first present these use cases in the context of policies and practices of the Harvard University Library (HUL) Digital Repository Service (DRS), a large-scale preservation and access repository currently managing more than five million digital assets and 21 TB, and then provide comprehensive instruction on the use of the JHOVE tool to implement these practices, as well as additional information necessary to facilitate the deployment and customization of JHOVE in local repository and preservation systems and workflows.
Benefits:
Intended Audience: Digital repository and preservation practitioners. Stephen Abrams, digital library program manager at the Harvard University Library, provides technical leadership for strategic planning and coordination of the Library's digital systems, projects, and assets.
