CLF/Mekano is a distributed object infrastructure oriented towards the high-level coordination of coarse grain components. Unlike other infrastructures of the same class, such as CORBA or DCOM, coordination in CLF/Mekano is built-in at the lowest level, namely at the inter-component communication protocol level, and not as a side service (such as the event,(More)
Nowadays people have to deal with an increasing amount of information contained in electronic documents available from numerous heterogeneous, widely distributed sources. Keeping up to date with recently published material relevant to a particular topic has become a challenge in itself. The Yaka system aims at facilitating this task by providing(More)
This paper describes how achieving consistent colour reproduction across different devices is a complicated matter. Although there is a technological infrastructure for managing colour across devices this is very rarely used as intended. This infrastructure has been created by modelling the problem of colour management as a wholly technical one. In this(More)
This article illustrates how to easily address scalability issues within distributed applications built on top of the Coordination Language Facility (CLF) middleware. CLF provides a distributed object computing framework with high expressiveness, flexibility and dynamicity. Our solutions rely on a core set of techniques such as replication, caching and(More)
In this paper we propose a new probabilistic approach to red eye detection and correction. It is based on stepwise refinement of a pixel-wise red eye probability map. Red eye detection starts with a fast non red eye region rejection step. A classification step then adjusts the probabilities attributed to the detected red eye candidates. The correction step(More)
System Overview The amount of information available from electronic sources on the World Wide Web and other on-line information repositories is highly heterogeneous and increases dramatically. Tools are needed to extract relevant information from these repositories. The Constraint-Bused Knowledge Bakers project (CBKB) at RXRC Grenoble realizes sophisticated(More)
This paper proposes the Resource-Based Programming paradigm as support for the design, implementation, debugging and tuning of distributed applications. This paradigm considers components as resource managers and expresses the application logic through scriptable transactional resource manipulations. In this paper, we describe the benefits deriving from(More)
Crowdsourcing is a relatively new model of labor where both the workers and work providers are experiencing its growing pains. A dominant platform that implements this model of labor is Amazon Mechanical Turk (AMT). While AMT has evolved over the years, the changes have focused mainly on work providers and have not addressed the problems workers face (e.g.(More)
