Segmentation of moving objects in an image sequence is one of the most fundamental and crucial steps in visual surveillance applications. This paper proposes a novel and efficient method for detecting moving objects in a noisy background by using a growing self organizing map to construct the codebook. The segmentation process distinguishes between those parts of the objects which move on static and dynamic background spaces such as roads and waving trees, respectively. The advantage of the proposed method is creating a small codebook based on the input pattern to model the background which results in less computational complexity and increases the speed of segmentation. We compare the proposed method with three other background subtraction algorithms and show that the proposed method has a higher precision and detection rate in comparison with other methods.

This paper presents a method to accurately identify the yaw-dynamic model of an unmanned helicopter. First, the model's structure is established by dynamic analysis. Then the model is reconstructed into a combination of three second-order subsystems. As the distribution of the damp ratios and natural frequencies of a second-order subsystems is limited, the model can be accurately identified from real-flight-test data. Finally, experiments are carried out to identify the yaw dynamic model. Results shown the modeling accuracy is improved through this approach.

This paper provides an update of the existing eParticipation research state of the art, and a longitudinal analysis of the development of the eParticipation field based on a shared framework of analysis. Drawing on a literature search covering the period from April 2006 to March 2011 included, 123 articles are identified, analysed and classified within the categories of eParticipation actors, activities, contextual factors, effects, and evaluation. Findings show that the field has a high level of dynamism, as focuses on eParticipation activities, contextual factors and effects have shifted in time, sometimes in counterintuitive directions. Drawing on the analysis, the conclusion section provides inputs for a research agenda. These include the need to move beyond a technological perspective, and encouraging the ongoing shift of research focus from government to citizens and other stakeholders.
