This content-based image search and automatic learning-based linguistic indexing project was started in 1995 when James Z. Wang developed an art image retrieval system for the Stanford University Libraries. He has later worked for the IBM QBIC project, the NEC AMORE project, and the AI Center of SRI International. From 1999 to 2000, the project was funded by the National Science Foundation under the TID (Trusted Image Distribution) project (PI: Gio Wiederhold). TID is part of the NSF Digital Library Initiative II (DLI-II) program. The technology research has been continued at Penn State University since 2001, with funding from the National Science Foundation ITR (PI: James Z. Wang), PNC Foundation, and SUN Microsystems. If you have any questions or comments about the image retrieval project, please send a message to James Z. Wang (jwang AT ist.psu. edu).
