During the past several years I have been the principal investigator and technical lead of our group's projects to deliver and visualize massive anatomical datasets including the visible human, the 4D visible mouse, and now C. elegans electron microscopy reconstructions in collaboration with David Hall and his team in The Center for C. elegans Anatomy at the Albert Einstein College of Medical and Richard Fetter in Cori Bargmann's lab at The Rockefeller University. My first projects at PSC were in collaboration with Drs Michael Becich and John Gilbertson in the Department of Pathology at the University of Pittsburgh Medical Center to store, process and disseminate a database of pathology images and use the data for automated pathology diagnosis. My particular part of that work was centered on the analysis of microscopic prostate cancer images and techniques for comparison and retrieval of images based on signature measures.
During the summer of 1995 I completed a test of my homegrown OCR system, Aurora, on an interesting and relatively rare 956 page book of historical interest - the 1849 Transactions of the American Medical Association. (It was not a good idea to get sick in 1849!) Processing of this text proved to be impossible with available commercial OCR products that were tried. See this page from the University of Pittsburgh Libraries for a bit more information about that project. Aurora has been in development on an "hour here an hour there" basis since 1988. Previously I had worked on the image storage, display and delivery components of Project Mercury, an electronic library project at Carnegie Mellon. My main contribution was "the world's fastest" FAX Group 4 decoder and viewer.
