Research Demos

the RIEMANN Research Project - Research on Intelligent Media Annotation

This content-based image search and automatic learning-based linguistic indexing research was started in 1995 when Wang developed an art image retrieval system for the Stanford University Libraries. If you are interested in using our technologies, please contact James Z. Wang and Jia Li.

Inspired by the fact that the Riemann Hypothesis remains as one of the most important unsolved problems in mathematics, we attempt to tackle the problem of intelligent media annotation, one of the most important unsolved problems in computer and information sciences.

The copyrights of the images belong to the owners of the images. Some images are used in the scholarly papers or demos for the purposes of teaching, scholarship or research, which are considered as "Fair Use" because (1) the amount of copyrighted work used in the scholarly works is reasonable, (2) the importance of that part of the work is not substantial to the whole work, and (3) the effect of the use upon the value or potential value of the copyrighted work is not significant.
