In view of the learning and improvement ability of on-line boosting algorithm framework, implemented a target tracking system which mixed color information and Haar-like features together. To solve the shortage of the Haar-like features, first used color histogram equalization to the frame image to enhance the image's color information, then used Bhattacharyya coefficient to calculate the similarity...
High-resolution functional magnetic resonance imaging (hi-res fMRI) methodology offers an opportunity for neuroscientists to gain insight about brain activities at a finer scale, and is thus becoming increasingly common. Traditional voxel-wise general linear model (GLM) is not suitable for hi-res functional brain mapping because local averaging may lose valuable fine-grained information boasted by...
As the scale of complex system is growing larger and larger, a small interference from internal and outer system can disturb the subsystem. Urban village reform system is an automatic, non-linear, complex system. In this paper, we evaluating the urban village reform system based on catastrophe progression method. Dividing complicated target into small events, then recursion operation is found with...
Wireless sensor networks are expected fine monitoring in all kinds of environments, but many of these environments, especially the forest, send our wireless sensors transmitting into bad conditions. Reflections and scattering from foliages, collision of simultaneous transmissions, attenuation of the signal, and many other factors make transmission worse and worse. And conditions become extremely awful...
This paper first presents a brief overview of two Layer 2 VPN technologies, the PBB and the H-VPLS. Along with the classification of the service requirement in power data network, the application of VPN technology in power data network has been analyzed. At last, this paper designs the solution of PBB interoperating with H-VPLS VPN in power data network, which enhances power data network scalability...
We introduce a cone flank routing model for balancing traffic load in multi-hop wireless networks. When routing along shortest paths, the nodes that are centrally located forward a disproportionate amount of traffic, the nodes at the centre will be much more congested than ones at periphery. However the maximum load can be decreased if the packets follow a cone flank. We map all nodes uniformly on...
