A new approach for bridging over the semantic gap is presented. This approach is based solely on the extraction of low-level illumination features, and by using well defined film rules regarding scene lighting, it generates high level semantic descriptors for scenes. These illumination descriptors could be further combined with other descriptors like motion and shot tempo, to generate a more co...

Introduction With the gradual promotion and implementation of China’s national innovation-oriented strategy, research universities are playing an irreplaceable role in leading scientific development and technological innovation. Scientific research is one of the basic functions of a research university, which cultivates high-quality innovations and supports research universities in serving thei...

The UK Worshipful Company of Information Technologists organised two high-level colloquia to debate ethical & spiritual implication of the new IT & Telecoms Environment in 1997. The colloquia were hosted in the UK House of Lords. This paper summarises the debates of those colloquia, and discusses some of the ethical and cultural issues that arise.

In the work here presented, we apply textual and sequential methods to assess the outcomes of an unconstrained multiparty dialogue. In the context of chat transcripts from a collaborative learning scenario, we demonstrate that while low-level textual features can indeed predict student success, models derived from sequential discourse act labels are also predictive, both on their own and as a s...

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 ...
