Video summarisation techniques aim to abstract the most significant content from a video stream. This is typically achieved by processing low-level image, audio and text features which are still quite disparate from the high-level semantics that end users identify with (the ‘semantic gap’). Physiological responses are potentially rich indicators of memorable or emotionally engaging video conten...

In this paper we propose a language-driven approach for the high-level design of web-based learning applications. In our approach we define a domainspecific language that characterizes the key application aspects. Then we assign a suitable operational semantics to this language, and we keep it independent of lowlevel implementation details such as interaction / presentation or database updating...

The term hyperheuristic was introduced by the authors as a high-level heuristic that adaptively controls several low-level knowledgepoor heuristics so that while using only cheap, easy-to-implement lowlevel heuristics, we may achieve solution quality approaching that of an expensive knowledge-rich approach. For certain classes of problems, this allows us to rapidly produce effective solutions, ...

We present an extension to indexicals to describe propagators for global constraints. The resulting language is compiled into actual propagators for different solvers, and is solver-independent. In addition, we show how this high-level description eases the proof of propagator properties, such as correctness and monotonicity. Experimental results show that propagators compiled from their indexi...

Extending AspectJ to experiment with new language features can be cumbersome, even with an extensible implementation. Often, a language designer only needs a rapid prototyping environment, but has to deal with a full compiler infrastructure, and must address low-level implementation issues. This work completes a lightweight extensible implementation of AspectJ with a declarative assimilation la...

This work consists in the study, development and implementation of a toolbox for image processing using the Python language and the Numerical Python package. This set has “open source” distribution and is adequate for multidimensional mathematical processing. Python is a modern and well projected language, interpreted, “very-high-level”, object oriented and extremely portable, apart from being ...

A new methodology for the design of DES control is proposed which allows for the creation of conceptual designs by using encapsulated low-level elements. The approach can be used within the standard framework of modular supervisory control. The notion of DES templates is introduced, where both DES modules and specifications are represented as high-level abstractions of typical behaviors. The co...
