A scalable re-ranking method for content-based image retrieval
(Information Sciences, 2014-05-01) [Artigo]
Content-based Image Retrieval (CBIR) systems consider only a pairwise analysis, i.e., they measure the similarity between pairs of images, ignoring the rich information encoded in the relations among several images. However, ...
Unsupervised manifold learning using Reciprocal kNN Graphs in image re-ranking and rank aggregation tasks
(Image And Vision Computing, 2014-02-01) [Artigo]
In this paper, we present an unsupervised distance learning approach for improving the effectiveness of image retrieval tasks. We propose a Reciprocal kNN Graph algorithm that considers the relationships among ranked lists ...
