一种基于分块的遥感影像并行处理机制
A mechanism of remote sensing image for parallel processing base on splitting blocks
摘要
Abstract
Large-scale parallel computing under cluster architecture is the basis of HPCChigh performance computing). To enhance the efficiency of image processing for remote sensing depends on the application of technology of parallel computing. Towards the characteristic about the scarce quantity of objects on some images, this paper proposed an algorithm model for task allocating and image processing under distributed computing environment. Firstly, we split the area of image which contains the objects using quad-tree policy, and dispatched the data to computing node by using the idea on dynamic load balance to perform this computing. Experiment shows that the strategy on task allocation can improve the overall computing performance effectively.关键词
