Radiology Database Images Retrieving

Oracle database offers the facility of searching and retrieving content-based multimedia objects such as audio, video, image or electronic documents, after a signature. There are different methods for signature generation for each specified object. The content-based image retrieval (CBIR) in Oracle may be realized on a linear search and comparison of the signatures using different parameters, or by image indexing, which are methods available in Enterprise Edition of Oracle Database. medBase is a dedicated application that uses Oracle interMedia for CBIR. Oracle has the possibility to integrate Java classes that offers more flexibility to a programmer in generating and processing the database objects. The chosen technology implemented in this paper is based on JSP, which is capable of realizing distributed web applications, and it can directly access the Java classes and methods offered by Oracle. The dedicated application was tested using different types of radiological images stored in an Oracle database.
