[SOA] next OhioDIG meeting - Sept 7

[Gemmill,Laurie]

> 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.
