<FONT COLOR="#000000" SIZE=2 FACE="Arial">11:15-12:00 noon</FONT> <FONT SIZE=2 FACE="Arial">Peter Murray from OhioLINK will give a presentation entitled "Access, Preservation, and Interchange: Digital Imaging with JPEG 2000" in the Kilgour Auditorium.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">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.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">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.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">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.</FONT></P>
<P><FONT COLOR="#000000" SIZE=2 FACE="Arial">12:00-1:00</FONT> <FONT SIZE=2 FACE="Arial">Lunch and discussion will follow the presentation in the Kilgour Private Dining Room. Lunch will be available for purchase at the OCLC Cafe.</FONT></P>
