Diagrammatic Vs Textual Query Languages: A Comparative Experimentses. This also implies the involvement of the user in the activities of design and testing of any interface. However, very few studies aiming at validating the usability of a system have been proposed in the database field, in contrast to many other computer science areas. In this paper we present a

Feature Based Digital Video Indexing from an image sequence processing perspective. This work proposes a methodology for designing video indexing schemes which use low level . indices to map into the set of application specific .. The indexing procedure uses image sequence processing and application requirements analysis to arrive at

Dynamic Object Clustering for Video Database Manipulationsthe dynamic grouping of objects to form a new object or cluster, and within each cluster a set of roles may be employed and/or introduced to define the behavior and interactions of the objects. In the context of a video database system, we examine the types of video data objects that require these e

Iconic Retrieval by Contents from Databases of Cardiological Sequencestents and the specification of content-oriented queries. A number of such techniques have been proposed in the literature but all of these consider images representing un-deformable rigid shapes. In this paper, the case of time-varying imaged curves is addressed with reference to a database of cinea

Data models, visual representations, metaphors: how to solve the puzzle?lso, the issue of singling out the relationships existing between the above two concepts and the data model was addressed. An introduction by the panel organizer together with a short position statement by each panelist are reported in the following document.

The Design of 3D Metaphors for Database Visualisation to visualise both query construction and result representation. The designs behind Amaze are introduced, and the visualisations of a prototype implementation are shown. It is felt that just as word processors have changed how people interact with document processing, so to could database visualisat

Issues in Visualizing Large Databasesrying large scientific databases are designed to visualize as many data items as possible on current display devices. Even if we are able to use each pixel of the display device to visualize one data value, the number of data items that can be visualized is quite limited. Therefore, in our system we
