Network access to XML data embedded in JPEG2000 images
Matthew Calder, Jacob Asiedu, and Robert A. Morris, University of Massachusetts at Boston Department of Computer Science, U.S.A.We will give a brief overview of the structure of JPEG2000 files and the unusual mechanism they provide by which internet connections can be made /into/ such files, extracting not only Regions of Interest (ROIs) in the image(s) in the file, but also remote extraction of XML data embedded in them. We will sketch future development, by which remote invocation of XPath or XQuery requests into embedded XML We will illustrate with a system in which ROIs can be semi-automatically added as so-called Media Resources to an SDD file that is itself embedded in the JPEG2000 file. This collaboration between an ROI editor and an SDD editor suggests that interface standards should be developed by which JPEG2000-aware applications can cooperate locally or across the network.
