X-ray Categorization and Retrieval on the Organ and Pathology Level, Using Patch-Based Visual Words

Uri Avni, Hayit Greenspan, Eli Konen, Michal Sharon, Jacob Goldberger
2011 IEEE Transactions on Medical Imaging  
In this study we present an efficient image categorization and retrieval system applied to medical image databases, in particular large radiograph archives.  ...  The methodology is based on local patch representation of the image content, using a "bag of visual words" approach.  ...  Retrieving similar cases from a large archive is a very challenging task and is one of the key issues in the rapidly expanding domain of content-based medical image retrieval [11] .  ...

Multimodal biomedical image retrieval using hierarchical classification and modality fusion

Md Mahmudur Rahman, Daekeun You, Matthew S. Simpson, Sameer K. Antani, Dina Demner-Fushman, George R. Thoma
2013 International Journal of Multimedia Information Retrieval  
For the CBIR search, several visual features were extracted to represent the images. Modalityspecific information was used for similarity fusion and selection of a relevant image subset.  ...  To minimize limitations of low-level feature representations in content-based image retrieval (CBIR), and to complement text-based search, we propose a multi-modal image search approach that exploits hierarchical  ...  In this regard, for off-line learning on training samples we used our best image and text-based MAP scores from the previous year (e.g., CLEF'2011).  ...
