Good morning,
Following the successful initial meeting of the Ohio Digitizer's
Interest Group, the next OhioDIG meeting will be on Wednesday, September
7, 2005 at OCLC.
About the Meeting
11:15-12:00 noon Peter Murray from OhioLINK will give a presentation
entitled "Access, Preservation, and Interchange: Digital Imaging with
JPEG 2000" in the Kilgour Auditorium.
For many years, libraries and archives have used the JPEG and TIFF
coding standards to store and make available images in an electronic
format. Decades of research in image compression techniques as a
subfield of signal processing have yielded advancements through the use
of wavelet transformation, and some have adopted products based on
proprietary wavelet compression implementations such as SID.
In the 1990s, under the auspices of the International Standards
Organization and the standards section of the International
Telecommunication Union, the Joint Photographic Experts Group worked to
create a new imaging standard using wavelet compression. The work of
the committee reached a pinnacle in December 2000 with the ratification
of Part 1 of the JPEG 2000 standard. As JPEG 2000 is embraced by
specialized vertical markets (such as medical imaging and national
defense intelligence gathering) and appears in the consumer digital
camera and scanner markets, it has the potential to revolutionize common
practices in libraries and archives. In addition to achieving greater
magnitudes of compression with reduced or no loss of image data, JPEG
2000 was designed to embed the technical and descriptive metadata
associated with images that has become crucial to long-term usability of
the image file as a digital artifact.
This briefing will present an overview of the JPEG 2000 image
compression technology and the defined JPEG 2000 file formats. The
overview will be followed by an outline of the implications of moving to
a JPEG 2000 practice for cultural heritage materials.
12:00-1:00 Lunch and discussion will follow the presentation in the
Kilgour Private Dining Room. Lunch will be available for purchase at
the OCLC Cafe.
