In any communication, security is the most important issue in today’s world. Lots of data security and data hiding algorithms have been developed in the last decade, which worked as motivation for the research. In the era of internet, in every communication images play a very important role. Images are used for secret communication also like for military purposes, hiding the serial number or co...

In this paper we present a conferencing architecture compliant with the IP Multimedia Subsystem (IMS) specification. To the purpose, we embrace a practical approach, by describing an actual implementation of an open source centralized video-conferencing system, called CONFIANCE, capable to offer advanced communication experience to end-users through the effective exploitation of mechanisms like...

An implementation of a particle system as part of the rendering pipeline of a 3-D computer game is described. Due to the interactive nature of such a computer game one of the most important issues in this implementation is the real-time rendering capability of the created special effects. A short summary of the game’s rendering pipeline is given, restrictions on special effects without a partic...

Communication media have become the primary way of interaction thanks to the discovery and innovation of many new technologies. One of the most widely used communication systems today is video streaming, which is constantly evolving. Such communications are a good alternative to face-to-face meetings, and are therefore very useful for coping with many problems caused by distance. However, they ...

One of the most important issues in web mining is how to find out similarities between web pages. In this paper we propose a method based on distributed learning automata which take advantage of usage data to find out web pages similarities. The idea of the proposed method is that if different users request a couple of pages consistently together, then these pages are likely to correspond to th...

My research involves developing models and tools to support architecture-level planning of large software evolutions. Over the past couple of years, we have developed a theoretical framework that we think encapsulates the most important issues in these kinds of evolutions, as well as formal models and tool prototypes within this framework. One important component of our framework involves the f...
