The current chapter presents and analyses an intelligent information system dedicated to scene modelling using the declarative design by hierarchical decomposition methodology. The aim is to develop a set of rules and standards, which constitute a functional process and data framework covering a wide range of similar systems. The basic mechanisms of the specific design process models are exposed....
A review of declarative scene modeling techniques is presented in this paper. After a definition of the purpose of declarative modeling, some existing declarative modelers are classified according to the manner to manage imprecision in scene description. Then, a concrete application is described, using constraint satisfaction techniques in the framework of Declarative Modeling by Hierarchical Decomposition...
Declarative modelling allows the designer to describe a scene, without the need to define the geometric properties, by specifying its properties which can be imprecise and incomplete. Declarative modelling by hierarchical decomposition is a special approach which gives the user the ability to describe a scene by top-down decomposition at different levels of detail, generates a set of geometric solutions...
The current chapter presents an integrated approach towards the enrichment of a scene modeling information system with intelligent characteristics with respect to user preferences. The aim is to set a framework for this purpose covering the entire range of the scene modeling process, from the abstract definition to the final visual outcome. Necessary notions from preference modeling, decision analysis...
Contemporary scene design problems are inherently complex and require multiple designers to work collaboratively. This chapter is concerned with the contribution to the development of collaborative systems for declarative modelling by hierarchical decomposition in scene modelling. Furthermore, it presents the development and evaluation of an effective collaborative prototype environment which facilitates...
The synthesis of 3D scenes is a very complicated task in computer graphics. In general, there is a lack of systems that would enable users to utilise aesthetic aspects during the early stages of scene synthesis. The synthesis of aesthetic character of a scene is a complex and intrinsic problem in many design domains. In this chapter, we report a research project that supports the hypothesis that it...
Web sites are likely to be regularly scanned and attacked by both automated and manual means. Intrusion Detection Systems (IDS) assist security analysts by automatically identifying potential attacks from network activity and produce alerts describing the details of these intrusions. However, IDS have problems, such as false positives, operational issues in high-speed environments and the difficulty...
