In this paper, we present a method to synthesize high-quality virtual viewpoint image targeting the detailed texture objects. About 30 images are taken from multiple uncalibrated cameras around the object, and the Visual Hull model is reconstructed with Shape from Silhouette method. To deform 3D surface model that is converted from Visual Hull Model using the information such as image texture a...

The use of haptic virtual fixtures is a potential tool to improve the safety of robotic and telerobotic surgery. They can “push back” on the surgeon to prevent unintended surgical tool movements into protected zones. Previous work has suggested generating virtual fixtures from preoperative images like CT scans. However these are difficult to establish and register in dynamic environments. This ...

Recent advances in Information and Communication Technology (ICT) provide an opportunity to build a self growing and sharing virtual environment for teaching and learning. Cloud computing is one of the latest technological advancement in ICT domain. Cloud computing technologies have changed the way applications are developed and accessed. A Virtual Learning Environment (VLE) is a system for del...

this study deals with the visibility, influence rate of diffrent links in virtual universities websites. the current community research is consisted of websites of 21 non medical universities websites and 8 websites of iran medical universities. the websites have been retrieved by the use of searchin and goolge webometic tools and are downloaded on personal computers to analyze their links. the...

Most virtual database systems are suitable for environments in which the set of member information sources is small and stable. Consequently, present virtual database systems do not scale up very well. The main reason is the complexity and cost of incorporating new information sources into the virtual database. In this paper we describe a system, called Autoplex, which uses machine learning tec...

The Virtual Network Mapping Problem arises in the context of Future Internet research. Multiple virtual networks with different characteristics are defined to suit specific applications. These virtual networks, with all of the resources they require, need to be realized in one physical network in a most cost effective way. Two properties make this problem challenging: Already finding any valid ...

In this paper, we proposed a secure mobile virtual computing environment for agent handshake. In mobile virtual computing environment, agent handshake often appears in mobile virtual computing, we conclude that problem into a basic secure problem. In this paper, we propose an ID-based one round authenticated group key agreement protocol with bilinear pairings for solving agent handshake problem...
