In this paper a new algorithm to compute the component tree is presented. As compared to the state-of-the-art, this algorithm does not use excessive memory and is able to work efficiently on images whose values are highly quantized or even with images having floating values. We also describe how it can be applied to astronomical data to identify relevant(More)
Significant research work has been conducted in software engineering to facilitate and speed up the process of service creation by experienced developers. Recently, however, service creation by ordinary users has attracted more and more attention as non-technical people have begun to play an active role in service life cycles, especially in a Web 2.0(More)
Reusing service capabilities to implement different integrated services in Next Generation networks (NGN) provides flexible and open service architecture capable of creating innovative services that do not need to be standardized and are based on the standardized service capabilities. In this architecture, invoking each integrated service may provoke the(More)
Evolutions of communications and the advent of Web real time technologies are further challenging the Telco ecosystem. New architectures are emerging to enable new services in a context where assets as identity, signaling and network management are decoupled and virtually delaminated, so to speak. This paper tackles three challenges to face to enable Telco(More)
Telecommunication services are rapidly increasing with the network growth towards the Next Generation Networks (NGN). The main problems of this growth are the extreme difficulty of service management and the introduction of new services. To address these issues we believe that we need to share common understanding of the term Service. We present a(More)
Telecom services are usually described from an applicative perspective. Service providers should yet describe formally what their services do for their users, in order to adapt them to user's needs and to compose them. We propose here a framework to describe communication services from a usage perspective, by describing formally the actions of the service(More)
This paper discusses the impacts of the emerging multimedia voice and data services on telecom intelligence distribution model. If the usual switching model and Internet model are insufficient for these services, the NGN model provides a good starting point. However, even NGN model presents some lacks on intelligence distribution aspects. Based on the(More)
Next generation networks (NGN) introduces a great emphasis on creating innovative telecommunications services that are rapidly deployed and tied to users need. Telecom operators and Service Providers are therefore facing important challenges to manage the overloaded data of the user preferences, the customized services and the whole service delivery chain.(More)
