According to the heterogeneous characteristics of wireless mesh networks and the QoS requirements of multimedia applications, we design a novel QoS adaptive architecture for WMNs that is cross-domain, cross-layer and cross-node. Furthermore, this architecture is mathematically described by using a bi-level programming model. This model uses the optimization results of subnets as the optimization parameters...
A novel adaptive object tracking algorithm with particle filtering and improved GVF-snake is proposed in this paper. Firstly, the initial contours of objects are obtained by using the background differencing method, and through the powerful searching ability of GVF-snake, the snake can be converged to the real contours of objects; by using the increasing or decreasing contour point algorithm according...
We propose a new 3D image segmentation method based on prediction, block-matching and partial 3D constraint in this paper. The algorithm only needs to set a few key points in the first image. We use intensity information and block-matching to optimize the initial condition, and consider the 3D object's characteristics at the same time. By using the partial 3D constraints we can get the result of 2D...
