In recent years, the convergence of computer vision and computer graphics has put forth new research areas that work on scene reconstruction from and analysis of multi-view video footage. In free-viewpoint video, for example, new views of a scene are generated from an arbitrary viewpoint in real-time using a set of multi-view video streams as inputs. The analysis of real-world scenes from multi...

Knowledge Discovery in Databases (KDD) is a highly complex, iterative and interactive process that involves several types of knowledge and expertise. In this paper we propose to support users of a multi-view analysis (a KDD process held by several experts who analyze the same data with different viewpoints). Our objective is to enhance both the reusability of the process and coordination betwee...

Multi-viewpoint modeling is an effective technique to deal with the ever-growing complexity of large-scale systems. The evolution of multi-viewpoint system specifications is currently accomplished in terms of fine-grained atomic changes. Apart from being a very low-level and cumbersome strategy, it is also quite unnatural to system modelers, who think of model evolution in terms of coarse-grain...

This paper proposes a new color calibration method for multi-viewpoint images captured by sparsely and convergently arranged cameras. The main contribution of our method is its practical and efficient procedure while traditional methods are known to be labor-intensive. Because our method automatically extracts 3D points in the scene for color calibration, we do not need to capture color calibra...

The free viewpoint switching is one of the most important features of multi-view video streaming. The key problem lies in how to achieve the best performance when the camera processing capability and the network bandwidth are limited. In this paper, we propose a novel free viewpoint switching scheme for multi-view video scenario, in which the distributed video coding technique is employed. In t...

(ABSTRACT) 3D video is the ultimate image medium recording a dynamic visual event in the real world as is. The recorded object can be observed from any viewpoint, because 3D video records an object's full 3D shape and its surface properties (i.e. color and texture). Recently, methods of creating arbitrary object views from multi-viewpoint images have been proposed. Although some methods do not ...

this research is based on explaining the relationship between globalization and al-qaeda. author believes that al-qaeda as an anti-globalization terrorist movement does its activities against the u.s hegemony over the world especially muslim world. from the other perspective al-qaeda uses professionally the globalization tools like information technology. describing globalization and reactions ...

Domain experts are skilled to build a narrow ontology that reflects their sub-field of expertise. It will be grounded on their work experience and personal beliefs. We call this type of ontology a single-viewpoint ontology. There can be a variety of such single viewpoint ontologies for a given domain that represent a wide spectrum of sub-fields and expert opinions on the domain. But to have a c...

An important dimension in the database technology evolution is the development of advanced/sophisticated database models. In particular, the viewpoint concept receives a widespread attention. Its integration to a data model gives a flexibility for the conventional object-oriented data model and allows one to improve the modeling power of objects. On the other hand, the viewpoint concept can be ...
