Abstract

With the expansion of the Internet, searching for information goes beyond the boundary of physical libraries. Millions of documents of various media types-such as text, image, video, audio, graphics, and animation-are available around the world and linked by the Internet. Unfortunately, the state of the art of search engines for media types other than text lags far behind their text counterparts. To address this situation, we have developed the Multimedia Analysis and Retrieval System (MARS). This article reports some of the progress made over the years toward exploring information retrieval beyond the text domain. In particular, the following aspects of MARS are addressed in the article: visual feature extraction, retrieval models, query reformulation techniques, efficient execution speed performance, and user interface considerations. Extensive experimental results are reported to validate the proposed approaches.
