We propose in this paper a method for extracting highlights from a sport TV broadcast. Unlike the existing highlights-extracting approaches our method does not require modeling of domainspecific events that are supposed to be interpreted by the user as highlights. Instead, we search for highlights at places where strong excitement is evoked in the user by the content of a video. It is namely re...

In model management, the Merge operator takes as input a pair of schemas, together with a set of mappings between their objects, and returns an integrated schema. In this paper we present a new approach to implementing the Merge operator based on semantic mappings between objects. Our approach improves upon previous work by (1) using formal low-level transformation rules that can be translated ...

We propose a new approach for video event learning. The only hypothesis is the availability of tracked object attributes. The approach incrementally aggregates the attributes and reliability information of tracked objects to learn a hierarchy of state and event concepts. Simultaneously, the approach recognises the states and events of the tracked objects. This approach proposes an automatic bri...

The development of large sample surveys creates new opportunities for analysis of subpopulations that would hitherto have been impossible to examine systematically. But it also raises key challenges. Low level measurement error can potentially lead to substantial biases in estimates drawn from small subsamples. This study details strategies researchers may take to make inferences in the context...

We present a real-time strategy (RTS) game AI agent that integrates multiple specialist components to play a complete game. Based on an analysis of how skilled human players conceptualize RTS gameplay, we partition the problem space into domains of competence seen in expert human play. This partitioning helps us to manage and take advantage of the large amount of sophisticated domain knowledge ...

Compact vision systems capable of capturing images at high speed and interpreting them to give users high-level information on the scene are increasingly becoming available to serve a range of real-time applications. This paper discusses the reality of miniaturised vision systemson-chip, the challenges which face their design, and their feasibility using modern and perhaps future technologies.

In this paper, we report on the status of the RoboCupJunior league, four years after it was founded. Since its inception in 2000, we have been surveying and/or interviewing students and mentors who participate in the international event. Here we present a high-level overview of this data. We discuss demographics of participants, characteristics of preparation and educational value. We highlight...

We give a translation of the visual description technique DiCharts to the synchronous language PURR. As a result, the design of a system can start with a graphical description technique at a very high-level and can then be automatically translated to the synchronous language PURR. This translation allows the further synthesis of the system and in particular, its verification.

Although information and communication technologies is beneficial for improving employee performance, frequently learning new technologies or extensively using technologies to work in non-working hours may lead to an increase of employee’s techno-invasion. However, little is known whether techno-invasion, a technostressor, causes employee job anxiety. Also, it remains unclear “when” techno-inva...
