Content-based query of image databases: inspirations from
text retrieval,
Pattern Recognition Letters,
21, 13-14, pp. 1193-1198, 2000. (Special edition: invited expanded papers from SCIA'99)
This paper reports the application of techniques inspired
by text retrieval research to content-based image retrieval. In
particular, we show how the use of an inverted file data structure
permits the use of an extremely high-dimensional feature-space, by
restricting search to the subspace spanned by the features present in
the query. A suitably sparse set of colour and texture features is
proposed. A weighting scheme based on feature frequencies is used to
combine disparate features in a compatible manner, and naturally
extends to incorporate relevance feedback queries. The use of relevance
feedback is shown consistently to improve system performance.
