Multi-modal relevance feedback for medical image retrieval
Dimitrios Markonis, Roger Schaer, Henning Müller · 2014
Medical image retrieval can assist physicians in nding information supporting their diagnosis. Systems that allow searching for medical images need to provide tools for quick and easy navigation and query renement as the time for information search is often short. Relevance feedback is a powerful tool in information retrieval. This study evaluates relevance feedback techniques with regard to the content they use. A novel relevance feedback technique that uses both text and visual information of the results is proposed. Results show the potential of relevance feedback techniques in medical image retrieval and the superiority of the proposed algorithm over commonly used approaches. Future steps include integrating semantics into relevance feedback techniques to benet of the structured knowledge of ontologies and experimenting on the fusion of text and visual information.
