RF*IPF: A Weighting Scheme for Multimedia Information Retrieval

Region-based approach has become a popular research trend in the field
of multimedia database retrieval. In this paper, we present the
Region Frequency and Inverse Picture Frequency (RF*IPF) weighting, a
measure developed to unify region-based multimedia
retrieval systems with text-based information retrieval systems. The
weighting measure gives the highest weight to regions that occur
often in a small number of images in the database. These regions are
considered discriminators. With this weighting measure, we can
blend image retrieval techniques with TF*IDF-based text retrieval
techniques for large-scale Web applications. The RF*IPF weighting has
been implemented as a part of our experimental SIMPLIcity image
retrieval system and tested on a database of about 200,000
general-purpose images. Experiments have shown that this technique is
effective in discriminating images of different semantics.
Additionally, the overall similarity approach enables a simple
querying interface for multimedia information retrieval systems.
