CMRS : Architecture for content-based multimedia retrieval.
Proc. Infotech Oulu International Workshop on Information Retrieval, Oulu, Finland, 179 - 190.

This paper presents a scalable and modular client-server architecture for content-based multimedia retrieval. The proposed architecture is designed to facilitate straightfoward addition of new media types and retrieval operations without modifications to existing features. This is achieved by the encapsulation of data, operations and user interface related to a particular media data or query entity into a single component. The encapsulation allows us to divide the system into a media independent platform and modular media specific extensions, which provide knowledge and functionality related to a specific media type such as still image or video. The current implementation includes CBIR extension, which allows realization of complex content-based queries of images based on example images, sketched or predefined personalized semantic concepts with different color, texture and shape attributes. Various experiments are carried out to demonstrate the functionality of the architecture.
