Abstract

Over many years, almost all research work in the content-based image retrieval (CBIR) has used Minkowski metric (or Lp-norm) to measure similarity between images. However, those functions cannot adequately capture the nonlinear relationships in contextual information given by image datasets. In this paper, we present a new similarity measure reflecting the nonlinearity of contextual information. Moreover, we propose a new similarity ranking algorithm based on this similarity measure for effective CBIR. Our algorithm yields superior experimental results on real image database and demonstrates its effectiveness.
