| 摘 要： | 针对面向对象的遥感技术中对象最优分割尺度难题,提出了基于分维的定量确定最优分割尺度算法。算法通过分析分维值变化规律和最优分割尺度之间的定量关系,发现分维值变化稳定区间与遥感对象最佳分割尺度范围相对应,因此可以通过对象分维-尺度关系,确定遥感对象的最佳分割尺度,一定程度上解决了最优分割尺度难于确定的难题。

| Abstract: | Aimed at the problem of determining the optimal segmentation scale in object-oriented remote sensing technology,we proposed an algorithm based on fractal quantitative measure to determine the optimal segmentation.According to analysis the quantitative relationship between variation of fractal dimension and the optimal segmentation scale,we found that the stable range of fractal dimension changes corresponded to the optimal segmentation scales of remote sensing object.Therefore,we could determine the optimal... |
