Video security is one of multi-view video applications. However the current multi-view video coding (MVC) software does not contain any rate control technique, this paper proposes a rate control algorithm for MVC based on the quadratic rate-distortion (R-D) model. The proposed algorithm adopts the fluid-flow traffic model, HRD (hypothetical reference decoder) and linear prediction model of MAD (the...
With the increasing number of technology areas using Virtual Machine (VM) platforms, challenges exist in Virtual Machine migrating from one physical host to another. This paper presents the design and implementation of a novel Hierarchical Copy Algorithm (HCA) for Xen live VM migration. Based on the memory characteristics which will be transferred, the measuring time of working sets is shifted to...
In the draft of multi-view coding (MVC), variable size motion estimation and disparity estimation are employed to select the best coding mode for each macroblock. These techniques achieve the highest possible coding efficiency, but they result in extremely large computation complexity which obstructs MVC from practical application. This paper proposes a fast mode size decision algorithm for MVC in...
Object migration is the movement of objects from one machine to another during execution. It can be used to enhance the efficiency and the reliability of grid systems, such as to balance load distribution, to enable fault resilience, to improve system administration, and to minimize communication overhead. Most existing schemes apply fixed object migration strategies, which are unadaptable to changing...
