With the advances in information technology, the amount o f m ultimedia data captured, produced, and stored is increasing rapidly. As a consequence, multi-media content is widely used for many applications in today's world, and hence, a need for organizing this data, and accessing it from repositories with vast amount of information has been a driving(More)
There is an accelerating demand to access the visual content of documents stored in historical and cultural archives. Availability of electronic imaging tools and effective image processing techniques makes it feasible to process the multimedia data in large databases. In this paper, a framework for content-based retrieval of historical documents in the(More)
Considering the fact that querying by low-level object features is essential in image and video data, an efficient approach for querying and retrieval by shape and color is proposed. The approach employs three specialized histograms, (i.e. distance, angle, and color histograms) to store feature-based information that is extracted from objects. The objects(More)
Considering the complexity a n d h uge volume of image and/or video data, eecient methods need to bedeveloped for querying multimedia databases. A well-known technique used for querying multimedia data is query-by-feature (e.g. color, shape, texture, size) of the objects residing in images and/or video frames. In this paper, we propose a tool for extracting(More)
The growing prevalence of multimedia systems is bringing the need for efficient techniques for storing and retrieving images into and from a database. In order to satisfy the information need of the users, it is of vital importance to effectively and efficiently adapt the retrieval process to each user. Considering this fact, an application for querying the(More)
Automated visual surveillance has emerged as a trendy application domain in recent years. Many approaches have been developed on video processing and understanding. Content-based access to surveillance video has become a challenging research area. The results of a considerable amount of work dealing with automated access to visual surveillance have appeared(More)
In different types of information systems, such as multimedia information systems and geographic information systems, object-based information is represented via polygons corresponding to the boundaries of object regions. In many applications, the polygons have large number of vertices and edges, thus a way of representing the polygons with less number of(More)

In this paper we report on our experiences in transitioning from an application framework for Command and Control systems to a product line engineering approach. The application framework has been developed in the context of Havelsan, a large company in Turkish defense industry. Large investments have been undertaken in the framework development to support(More)
Cultural heritage has been gaining more importance in the recent years in combination with sophisticated yet effective computer vision techniques. As a consequence, archaeological data, both in textual and image forms, has been considered in the development of database models. Archaeological sites are the primary source of archaeological data, and the(More)
