| 摘 要： | 变化检测技术是从观测数据中有效地提取各种变化信息.本文针对变化检测中差异影像的构造和变化阈值的确定展开研究,首先将两期的遥感影像矢量叠加,然后进行主成分分析获得变化量,最后通过区域扩散阈值确定方法获得变化检测结果.通过与传统变化检测方法的实验比较,证明了该方法的有效性.

| Abstract: | Change detection can obtain useful changed information from the observed data. In this paper, the change detection research is based on building difference image and threshold determination. Firstly, Two pe- riods of remote sensing image are superimposed~ and then principal component analysis is used to obtain change vector. Finally, the change detection results are obtained through regional diffusion for threshold de- termination. Compared with the traditional method, the proposed algorithm is effective. |
