Image Feature Evaluation for Contents-based Image Retrieval
Kuffner, A. and Robles-Kelly, A.
This paper is concerned with feature evaluation for
content-based image retrieval. Here we concentrate our attention
on the evaluation of image features amongst three
alternatives, namely the Harris corners, the maximally stable
extremal regions and the scale invariant feature transform.
To evaluate these image features in a content-based
image retrieval setting, we have used the KD-tree algorithm.
We use the KD-tree algorithm to match those features
corresponding to the query image with those recovered
from the images in the data set under study. With the
matches at hand, we use a nearest neighbour approach to
threshold the Euclidean distances between pairs of corresponding
features. In this way, the retrieval is such
that those features whose pairwise distances are small,
'vote' for a retrieval candidate in the data-set. This voting
scheme allows us to arrange the images in the data set in
order of relevance and permits the recovery of measures
of performance for each of the three alternatives. In our
experiments, we focus in the evaluation of the effects of
scaling and rotation in the retrieval performance. |
