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...

Definition: High-level concept detection is the process within which the high-level concepts or objects which are presented in a multimedia document are determined. For example, given an image, a detection scheme would reply that it contains concepts such as “sky”, “sand”, “sea”, the image depicts an “outdoor” and more specifically a “beach” scene. In some cases, the actual position of concepts...

This paper discusses a new design of chattering reduction for sliding mode control. Conventionally, a boundary layer around the sliding surface is used to achieve smooth control signals. However, the boundary layer design become in-effective in chattering reduction when there is high-level measurement noise. To solve this problem, this paper proposes a dynamic sliding mode control, which, with ...

Problem Task: combining multiple types of features for music classification from raw audio signals • Whether-we need multiple features? • How-to combine different features? • What-is the best feature and combination scheme? Features Taxonomy of audio features • Timbre features capture the quality of the sound and has much to do with the instrumentation of the music. • Temporal features capture ...
