Abstract: Tracking is a fundamental problem for event recognition. Particle filter (PF) is acknowledged for its efficiency in dealing with multi-modal visual tracking problem of general nonlinear and non-Gaussian system. It therefore emerged as an appealing tool for tracking objects in video sequences. Although many proposals have been put forward to deal with various scenarios and enhance PF convergence properties, it is acknowledged that comprehensive evaluations of the proposals are still lacking. This paper aims to contribute to this ongoing research. Especially, simulated videos were created to analyze the influence of the target appearance according to various noise intensities that entails …partial or full occlusion scenarios. In the simulated videos, the experiment provided more accurate conclusions given the range of involved factors, w.r.t target model, similarity measurement, and environmental distraction. To validate the conclusion from the simulated videos, the experiment was also conducted in the benchmark videos. Show more

Abstract: Multimedia has changed traditional white-blackboard lecture forever and reformed continually the forms and presentation of materials. In this paper, we propose an online marking system. The realization of this system will help improve working efficiency of marking papers, reduce potential cheating and facilitate the teacher storage and analysis students’ examination papers. The system is realized based on B/S structure (Browser/Server structure) which will increase the flexibility of online marking as long as the teacher accesses to the Internet. In the proposed system, some functions in OpenCV have been introduced in procedure such as image segmentation, image enhancement and image rectification …to make sure the picture which is shown to the reviewer is correct and clear.In database design of the system, we have fully considered the security issues and the data scalability, we adopt SQL server 2005 as our primary database to ensure comparable large storage capacity and throughout capacity. The system has realized online marking and the storage streamlined, which will improve teacher’s work efficient and provide a reference for learning schedule and a feedback to teaching achievements.

Abstract: With the advancement of multimedia, Internet of things, and cloud computing technologies, technology enhanced learning applications such as smart school and smart learning at home have been paid more attentions to. Cloud computing services, which provide a novel collaborative and personalized learning style, have an important impact on learning and teaching. However, with the rapid development of cloud computing, the energy consumption problem for cloud computing networks cannot be ignored and the idea of energy efficiency comes into being. Currently, the main method to solve energy consumption problem is to turn the idle routers and links into sleeping, but this …approach cannot be suited for cloud computing networks and may bring down network resource utility and network performance. This paper combining the Sleeping Redundant Links Algorithm (SRLA) with the Minimum Criticality Routing Algorithm (MCRA), proposes a Robust Energy Efficiency Routing Algorithm (REERA) used for cloud computing networks. The REERA uses the SRLA algorithm to sleep the redundant links in cloud computing backbone network, and then improves the robustness of the entire network by the MCRA algorithm. The REERA is able to dynamically change the link weight, ensure that most of the link can be used uniformly, and avoid the traffic congestion when certain links of cloud computing networks was excessively used. It thus improves the performance of the entire network. Comparing REERA with OSPF-based algorithm, the simulation results show that REERA outperforms Open Shortest Path First (OSPF) -based algorithm, and REERA can realize the energy-efficient routing algorithm under the premise of network robustness constraints.

Abstract: With the development of multimedia and Internet of things technologies, technology enhanced learning applications such as smart class and smart learning at home have received more attentions from industrial and academic communities. However, pervasive wireless communications, which builds new collaborative and personalized learning patterns, have an important impact on learning and teaching. For current pervasive wireless networks, spectrum resources become increasing lack due to the introduction of a large number of new wireless technologies and thus the access of many new devices to wireless networks for all kinds of applications such as online smart learning. How to exploit effectively spectrum …resources in current pervasive wireless networks is a larger challenge. To this end, we study dynamic access problem for spectrum resources. In this paper, we analyze more complex multiple channel model with multiple primary and secondary users. We exploit the lognormal distribution to characterize primary user behaviors and use opportunistic spectrum access to obtain the sensing status of channels. To raise the channel utility, we control transmission radiuses of secondary users to make primary and secondary users simultaneously utilize the channel. Finally, we propose the dynamic access algorithm to multiple channels. Simulation results show that our approach is feasible and promising. Show more

Abstract: This paper evaluated the use of Three-dimensional (3D) Computer Visual Materials (CVM) to support user participation in the early design stages for a private house. A qualitative approach was identified in two stages. Firstly, a semi-structured interview with a sample of architectural firms was conducted, and secondly, data was collected from conversational dialogues between an architect and a list of clients. The results revealed that various stages of the design process have different responses with respect to the use of Visual Material (VM) and its impact on user participation. In addition, there appeared to be a direct relationship between the …Level of Details (LoDs) and specific design stages. Show more

Abstract: The proliferation of knowledge-sharing communities has generated large amounts of data. Prominent examples of how user-generated content can be harnessed include IBM’s Watson question answering sytem and Apple’s Siri, the question answering application in iPhones. Facing such massive data, user authority ranking is important to the development of question answering and other e-commerce services. In this study, we propose three probabilistic models to rank the user authority of each question. Compared to the existing approaches focused on the user relationship primarily, our method is more effective because we consider the link structure and topical similarities between users and questions simultaneously. …We use a real-world dataset from Zhihu , a popular community question answering website in China to conduct experiments. Experimental results show that our model outperforms other baseline methods in ranking the user authority. Show more

Abstract: Generating class-agnostic object proposals followed by classification has recently become a common paradigm for object detection. Current state-of-the-art approaches typically generate generic objects, which serve as candidates for object classification. Since these object proposals are generic whereas the categories for classification are domain specific, there is a gap between the generation of object proposals and the classification of object proposals. In this paper, by taking advantages of the intrinsic structure and the complexity of each category of objects, we propose a novel tree-based hierarchical model to learn object proposals, from top proposals produced by the existing object proposals generation methods. …First, we develop a tree-structured representation for each object to capture its hierarchical structure feature. Second, we propose a 23D compact feature vector to represent objects’ visual features. Third, we formulate a learning schema which evaluates the objectness of each proposal. Experiments demonstrate the significant improvement of the proposed approach over the state-of-the-art method in terms of object detection rate. An application is proposed based on this approach to help children learn and recognize objects by their visual appearances and their sub-parts structures. Show more
