Content-based image retrieval for large biomedical image archives

Sameer Antani, L Rodney Long, George R Thoma
2004 Studies in Health Technology and Informatics  
Our research focuses on developing techniques for hybrid text/image query-retrieval from the survey text and image data.  ...  Content-Based Image Retrieval (CBIR) has been a topic of research interest for nearly a decade. Approaches to date use image features for describing content.  ...  These hybrid text/image queries can be very useful in medical image databases which often have supporting text information for the image data.  ...

Automatic construction of navigable concept networks characterizing text databases [chapter]

Claudio Carpineto, Giovanni Romano
1995 Lecture Notes in Computer Science  
Given any collection of texts, we first automatically extract a set of index terms describing each text.  ...  In this paper we present a comprehensive approach to conceptual structuring and intelligent navigation of text databases.  ...  Automatic Indexing The first task for building a conceptual representation of a text database is to identify the content of each text. Basically, there are two kinds of approaches.  ...
