摘要
通过对遥感影像处理算法中并行特性的分析,利用可编程图形处理器GPU的并行流处理特性和灵活的可编程性,实现基于GPU的遥感影像并行处理,在保证影像处理质量的前提下,大大提高了处理速度,能够满足一定情况下影像实时处理的要求。
It first introduces the remote sensing image parallel processing probability. Then it uses the latest programmability feature available in 3D cards in order to implement image parallel processing. And it proves the advantage of image processing based on GPU through experimentations.
