Abstract
Image retrieval algorithms are generally based on the
assumption that visually similar images are located close
to each other in the feature space. Since the feature vec-
tors usually exist in a very high dimensional space, a para-
metric characterization of their distribution is impossible,
so non-parametric approaches, like the k-nearest neighbor
search, are used for retrieval.
This paper introduces a graphtheoretic approach for
image retrieval by formulating the database search as a
graph clustering problem by using a constraint that re-
trieved images should be consistent with each other (close
in the feature space) as well as being individually similar
