A Correlation Graph Approach For Unsupervised Manifold Learning In Image Retrieval Tasks
(Elsevier Science BVAmsterdam, 2016)
Effective, efficient, and scalable unsupervised distance learning in image retrieval tasks
Various unsupervised learning methods have been proposed with significant improvements in the effectiveness of image search systems. However, despite the relevant effectiveness gains, these approaches commonly require high ...
Unsupervised rank diffusion for content-based image retrieval
Despite the continuous development of features and mid-level representations, effectively and reliably measuring the similarity among images remains a challenging problem in image retrieval tasks. Once traditional measures ...

Using a Markov Random Field for Image Re-ranking Based on Visual and Textual Features
(Revista Computación y Sistemas; Vol. 14 No. 4, 2011-06-06)
Abstract. We propose a novel method to re-order the list of images returned by an image retrieval system (IRS). The method combines the original order obtained by the IRS, the similarity between images obtained with visual ...
Combining pixel domain and compressed domain index for sketch based image retrieval
Sketch-based image retrieval (SBIR) lets one express a precise visual query with simple and widespread means. In the SBIR approaches, the challenge consists in representing the image dataset features in a structure that ...

Recognition-free Retrieval of Old Arabic Document Images
(Revista Computación y Sistemas; Vol. 15 No. 2, 2011-12-13)
Abstract. Searching of old document images is a relevant issue today. In this paper, we tackle the problem of old Arabic document images retrieval which form a good part of our heritage and possess an inestimable scientific ...
