| 摘 要： | 为了实现遥感影像的网络快速发布,提出了一种高效的影像金字塔模型的构建算法,影像的切割与重采样均在内存中运算完成,尽可能地减少I/O操作,从而提高其执行效率。提出了面向Internet的分布式遥感影像的切割算法,并给出了基于B/S架构和基于C/S架构的两种实现方式。为了保证算法的效率与分布式结构,利用C++与Java联合编程进行实现。通过实例对算法性能进行测试,证明了算法的可操作性、实用性和高效性。 |

| Abstract: | For quick publication of Remote Sensing(RS) images in Internet,this paper proposed an efficient algorithm to build image pyramid model. In order to improve the efficiency,both the image cutting and re-sampling are implemented in the RAM,avoiding the unnecessary I/O operations. Two distributed implementation approaches under Internet environment are presented,which are based on Browser/Server(B/S) and Client/Server(C/S) architectures respectively. They are programmed by combing C++ with Java,ensuring the pro... |
