A New Method for Virtual Machine Cluster Scheduling
Yu Shuchun,Qiu Lin,Liu Shuang 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.10
Aiming at the reasonable configuration of virtual cluster and physical host, a new virtual machine cluster scheduling method is proposed. First of all, according to the resource requirements of the task, select the resource conditions similar to the virtual machine cluster. In the clustering process, the CPU, memory, communication bandwidth and other parameters are integrated in a measure under. Secondly, with the help of minimum flow and maximum cut theory, the virtual machine cluster is divided and configured to complete the scheduling process of virtual machine to the corresponding physical host. Experimental results show that the virtual machine cluster scheduling based on this new method makes the resource utilization of the physical host higher.
Research on Camera Calibration method Based on Eight Parameter Model
Yu Shuchun,Liu Shuang,Yu Xiaoyang 보안공학연구지원센터 2015 International Journal of Signal Processing, Image Vol.8 No.9
Camera calibration is the basis for realization of image distortion correction. Because the causes of image distortion are very complex, it has become a difficulty to correct image distortion with calibration results. In order to reduce the complexity of the existing distortion correction method, an eight parameters camera calibration model was proposed in this paper. In this model, eight parameters were used in describing radial distortion and tangential distortion. The experimental results show that the proposed method can be easily solved and correct distortion accurately.
