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 ...
Multimedia Retrieval Through Unsupervised Hypergraph-Based Manifold Ranking
(Ieee Transactions On Image Processing, 2019-12-01) [Artigo]
Accurately ranking images and multimedia objects are of paramount relevance in many retrieval and learning tasks. Manifold learning methods have been investigated for ranking mainly due to their capacity of taking into ...
