A Multimedia Database Server: Implementation and Functions

The paper presents the implementation and performances of a Multimedia Database Server software tool used for managing medium sized image collections. The software tool uses traditional data types (integer, double, char, varchar) and a new complex data type, called image. This type is used for storing the image along with the information extracted. This refers to the image’s size and type, color and texture characteristics. An element of originality for this software is the content based retrieval module that allows the user to build content based visual queries to the image level. The server’s performances are studied from the quality of the retrieval point of view. For the tests there are used both color and texture characteristics which are automatically extracted.
