Therefore, a parallel geometry correction algorithm based on dynamic division-point computing, called PIWA-DDC, is proposed.
近年来,遥感图像几何校正的并行处理成为重点研究的对象·但现有的并行算法尚存在一些问题,这些算法不具备负载平衡能力或者全局计算量大,而且局部操作非常耗时·针对以上不足提出了一种基于动态分界点计算的并行几何校正算法PI WA-DDC·通过LogP模型,推导出PI WA-DDC算法具有良好的可扩展性·通过在MPP上的测试数据,验证了该算法具有良好的负载平衡能力和高效处理几何畸变的能力
A topological space (X,T) has property (wa) (property (a), respectively) provided for every open cover U of (X, T) and every dense set D there exists a subset F C D such that F is discrete (closed and discrete, respectively) and St(F,U) = U{U U : U F =0} = X.
设（X,T）是拓扑空间,如果对于任意的开覆盖U和任意的稠密子集D,存在X的离散子集F（?）D使得St（F,U）=U{U∈U:U∩F≠（?）}=X,则称（X,T）具有性质（wa）。
