Are We Moving Toward an Information SuperHighway or a Tower of Babel? The Challenge of Large-Scale Semantic Heterogeneity

Similarity Indexing with the SS-tree - Data Engineering, 1996., Proceedings of the Twelfth International Conference on

Eficient indezing of high dimensional feature vectors is important to allow visual information systems and a number other applications to scale up to large databases. In this paper, we define this problem as “similarity indexing” and describe the fundamental types of “similarity queries” that we believe should be We also propose a new dynamic structure for similarity indexing called the similar...

An analytic overview on the rise of cyber spaces and the Islamic Society: An urban challenge or natural transition of cities?

Moving toward third millennium is characterized by capabilities in transforming human life. Specially, development of information technologies in everyday life lead to great changes in communication tools andour current understanding ofurban social life. Indeed, telecommunications because of independency from time—space constraints, provide a new unlimited space for social interactions in globa...

Metadata Jones and the Tower of Babel: The Challenge of Large-Scale Semantic Heterogeneity

The popularity and growth of the “Information SuperHighway” (e.g., the Web) have dramatically increased the number of information sources available for use and the opportunity for important new information-intensive applications (e.g., massive data warehouses, integrated supply chain management, global risk management, in-transit visibility). Unfortunately, there are significant challenges to b...

Statistical Background Modeling Based on Velocity and Orientation of Moving Objects

Background modeling is an important step in moving object detection and tracking. In this paper, we propose a new statistical approach in which, a sequence of frames are selected according to velocity and direction of some moving objects and then an initial background is modeled, based on the detection of gray pixel's value changes. To have used this sequence of frames, no estimator or distribu...
