摘要
文章以某城市遥感影像为例,把欧式距离的方法运用于多时相遥感影像的变化检测中。分别对单像元与3×3窗口像元做变化检测,比较二者之间的效果,得出利用像元周边信息能够减少噪音,降低破碎度的结论。
The article uses a city as a example to explain the method of using continental distance for multiemporal remote sensing image changes.Comparing the results of single pixel and 3X3 pixels matrix,ones concludes that it can reduce noise and fragmentation to use the surrounding information of pixels.
