摘要
针对不同时相遥感影像中特定目标的变化,研究了基于特征提取的目标变化检测方法。该方法首先根据目标的几何特征进行检测与提取,然后对提取出的两目标影像进行比较,得到特定目标的变化。实验结果表明该方法对特定目标的变化检测有较好的效果。
To obtain the change of some objects in remote sensing images of the same region obtained in different time, this paper studied a method of change detection based on the special object extraction. First the special objects were respectively extracted from the two different images according to their geometry feature. Then we got the change of special objects by comparing the difference of two images. Results showed that this method had better effect on detecting the change of some special objects.
