  • David McG. Squire, Wolfgang Müller, Henning Müller and Thierry Pun, 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.
