摘要:

为了解决遥感影像聚类个数及中心点选取的问题, 提出了一种并行的中心矢量优化选取的遥感影像聚类算法(PCVOS: Parallelized Center Vector Optimized Selection Algorithm for Remote Sensing Image Cluster)。该算法引入模糊评价目标函数并给出了一种染色体评价机制, 提高聚类染色体在类目、空间划分的多样性; 同时引入MPI(Massage Passing Interface)多进程并行技术, 加快了算法运行速度。实验结果表明, 相对于传统的K-Means、ISODATA(Iterative Self Organizing Data Analysis Techniques Algorithm) 和ACDE(Automatic Clustering Differential Evolution)算法, PCVOS 不但可以获得更好的聚类效果, 而且可以充分利用并行资源加快算法运行速度。

Abstract:

In order to solve the problem of selecting the clustering number of remote sensing images and positions of center points, Proposed a PCVOS ( Parallelized Center Vector Optimized Selection Algorithm for Remote Sensing Image Cluster) which introduces fuzzy evaluation of the objective function and put forward an evaluation mechanism of chromosomes to improve the diversity of category and space division of clustering chromosomes is proposed. The MPI multi-process parallel technology is simultaneously introduced to speed up the running speed of the algorithm. The experiment shows that compared with the traditional K-Means, ISODATA(Iterative Self Organizing Data Analysis Techniques Algorithm) and ACDE ( Automatic Clustering Differential Evolution) algorithm, PCVOS can obtain a better clustering effect, and make full use of parallel resources to speed up the running speed of the algorithm.

Key words: cluster, remote sensing image, category number, parallel computing, optimized selection
