Feature propagation on image webs for enhanced image retrieval

Eric Brachmann, Marcel Spehr, Stefan Gumhold
2013 Proceedings of the 3rd ACM conference on International conference on multimedia retrieval - ICMR '13  
In cases where the visual appearance of semantically similar images differs largely, feature histograms mismatch and the model fails.  ...  The bag-of-features model is often deployed in content-based image retrieval to measure image similarity.  ...  It checks whether locations of matching features between the query and each top retrieval result are consistent by searching affine transformations between feature sets.  ...

Regularizing query-based retrieval scores

Fernando Diaz
2007 Information retrieval (Boston)  
Because of these strong empirical and theoretical results, we argue for the adoption of score regularization as general design principle or post-processing step for information retrieval systems.  ...  Document rankings derived from regularized scores, when compared to rankings derived from un-regularized scores, consistently and significantly result in improved performance given a variety of baseline  ...  Any opinions, findings and conclusions or recommendations expressed in this material are the author's and do not necessarily reflect those of the sponsor.  ...

2021 IEEE Access  
With the explosion of multi-modal Web data, effective and efficient techniques are in urgent need for cross-modal data retrieval with relevant semantics.  ...  Specifically, by jointly considering the content similarity, the correspondence and other weak correlation among cross-modal documents, we build the intra-modal similarity with multiple affinity subgraphs  ...  For Text→Image retrieval, the semantic gap between queries and visual data can be alleviated by modeling the intramodal visual affinity using feature combinations of database documents.
