With the development of display hardware, computing power, transmission and rendering algorithm, 3DTV is becoming the most promising technology that provides the users a more natural viewing experience than 2D displays. But most 3D movies need to wear 3D glasses to watch. Naked eye 3D is the ultimate goal of the development of 3D technology. Multi-view rendering by depth image based rendering (DIBR)...
Recent computer vision technology has made great progress in 3DTV industry. The advent of 3DTV to the home raises a number of challenges beyond the basic display of an available stereo pair. One of them is the production of 3D augmented contents. To present virtual objects over the real world, the existing method is offline processing in postproduction. It is a difficult and expensive work since flexible...
Current researches about multi-vehicle cooperation task assignment models, such as capacitated transshipment assignment problem (CTAP) and mixed integer linear programming (MILP), have extreme amounts of computation needed for the dynamic coordination planning of Unmanned Vehicles (UV) team. In this paper, we propose the Action-Seeking Team coordination (ASTC) model with an aim to promote the UV team's...
Depth generation is the key technology in the 3DTV system. Due to the demands for accuracy and real-time execution, local methods are more suitable, but the challenge is to decide an appropriate window for each pixel. We propose a novel local method, which constructs the support windows adaptively only based on the intensity, and the process has no relation with disparities. This is the main difference...
The effectiveness in communication and the great economization in time and cost make the video conference system become an important application today. If the video conference system can be constructed on Internet, its practicability and application value will be improved greatly. However, with traditional web page techniques, it is difficult to construct a video conference system that has many complex...
Distributed Virtual Environment (DVE) has attracted much attention in recent years due to the rapid advances in the areas of E-learning, Internet gaming, human-computer interfaces, and etc. However, the complexity of designing an efficient DVE greatly challenges today's researchers. Indeed, how to effectively measure a DVE or the design of DVE plays an important role in progressively guiding the DVE...
This paper describes an real-time classification method of power quality (PQ) disturbances based on DSP-FPGA. The proposed method simultaneously uses the results obtained in the application of a series of RMS values and the discrete Fourier transform to the power signal waveform. A series of RMS values are used for estimation of the time-related parameters of the PQ disturbances and the discrete Fourier...
Recent advances in Service Oriented Architecture (SOA) provides many exciting opportunities for developing next-generation of distributed simulation frameworks and tools. At the mean time, Peer-to-Peer (P2P) based network technique also challenges the traditional view of distributed simulations. Indeed, the integration of SOA and P2P techniques can potentially help on developing more flexible, scalable...
This paper presents a new local binocular stereo matching algorithm. A self-adapting matching score is used to measure the dissimilarity of two corresponding pixels. In matching cost aggregation step, we replace the cost of each pixel with the average cost of selected neighboring pixels based on edge pixels information to limit cost aggregation within the same segment, which can preserve the shape...
This paper presents a new local binocular stereo matching algorithm. A local window with adaptive support weights is used to aggregate matching costs. A more robust matching score is set up combining sum of absolute intensity differences and a gradient based measure. Each pixel has a different disparity search range according to disparity gradient analysis and computational complexity decreases rapidly...
Virtual simulation has been playing an important role in many areas including gaming, training, e-learning, and etc. At the mean time, real-time emergency response system is attracting more and more attention due to its significance to reduce the casualties and properties lost when disasters come. Indeed, a highly responsive and effective real-time response system depends on a well designed architecture,...
In wireless sensor networks (WSNs), timeliness is one of the most challenging problems for critical applications. Caccamo et al. designed a collision-free real-time MAC protocol for sensor networks by adopting the "cellular structure" in traditional telecommunication networks. They assumed that sensors are organized into many rigid hexagon cells and a router node is at the center of each...
QoS-aware service management and composition has become an interesting research topic with the rapid development of service oriented architecture (SOA). Differently with Web-services based systems, the emergence of peer-to-peer (P2P) based distributed network technology brings more challenge to the QoS-aware service management and composition. In this paper, we propose our design of a QoS-aware hierarchical...
A novel binary images edge detection method is presented. It directly clear the inner pixels of the images to obtain the edges. Connectivity-number were sought as detectors, those pixels that have zero-connectivity-number were eliminate as inner pixels from the image. Seventeen well-chosen templates change the computing into efficient exclusive or operations. Experimental results show that it provides...
