Advanced video surveillance applications require two successive steps: image analysis and content understanding. The first step analyses and extracts the characteristics of the video sequence. It defines the regions or the objects of interest according to their spatial/temporal properties. This analysis results in a segmentation of the video sequence that is interpreted by the content understan...

The authors present an integrated GIS tool, Accessibility Analyst, for accessibility analysis in urban transportation planning, built as an extension to the desktop GIS software package, ArcView. Accessibility Analyst incorporates a number of accessibility measures, ranging from catchment profile analysis to cumulative-opportunity measures, gravity-type measures, and utility-based measures, con...

Spatial analysis is a fundamental function for geographic information systems. Although it is popular in many commercial desktop GIS packages, this capability is very limited in a Web-GIS environment, especially when relational database is used for geospatial data management. This paper proposes and prototypes a methodology to enhance spatial analysis capabilities of Web-GIS by extending and en...

In the 1990s, one of the dominant modes of computation will be in graphics, picture and image processing. All applied fields will be affected although none more so than those areas such as spatial planning and decision-making whose modes of analysis and communication are based on maps. Already, Geographic Information Systems (GIS) are becoming widespread in management and planning, and their fo...

In the veterinary epidemiology, the advantage of mapping the locations of farms and other facilities with animals is obvious. In an outbreak of a disease it could make the management of the situation easier, and it could also provide a tool to evaluate different strategies to prevent the spread of infectious diseases. This paper aims to describe and give an overview of the possibilities and pot...

In recent years, Franz Liszt has garnered increasing interest among music theorists for his innovations in harmony and form. However, little attention has been given to rhythmic aspects of his compositional style: in particular, he frequently incorporates rich rhythmic structures in which the meter written in the score and the meter perceived by the listener are locked in an evolving conflict. ...

Sieber 15 Introduction Increasingly nonprofits are following the lead of public agencies and private industry by implementing a GIS. They are drawn to a GIS because it can combine large amounts of data from disparate sources and on different media, order them into layers or themes, and analyze or display various relationships. The greater promise of the technology, to nonprofits such as grassro...

GIS can be readily used to manage and analyze 2D information and also afford 3D visualization of surface features. However, general-purpose GIS packages do not offer capabilities for constructing or visualizing 3D geologic models. GIS tools must, therefore, be appropriately tailored to handle geologic data and accommodate the special spatial analysis needs of geologic information. Since 3D geol...

The security model proposed for the Geographic Information Systems (GIS) is a data, which is capable of visualizing technology and has the capability to apprehend, cache, verify, amalgamate, engineer and exhibit data with the help of digitized maps. It has enormous applications in the field of engineering, business management process, communication both in the private and public regions. A GIS ...
