| 摘 要： | 以往面向对象影像分析的分割尺度主要依靠经验并结合目视来进行选择,带有一定的主观性.本文针对利用高分辨率遥感影像进行土地利用信息提取的目的,采用面向对象的方法完成了两个典型实验区域的多尺度分割.主要研究了分割参数的选择；重点提出了一种最优分割尺度计算模型.结果表明,此模型计算最优分割尺度方便快捷,而且计算出的最优分割尺度...

| Abstract: | The authors accomplished the multi-scale segmentation for two typical experimental areas—agricultural area and architectural area in order to extract land-use information from high resolution remote sense imageries.They researched mainly how to select the segmentation parameters,especially proposed an optimal segmentation scale arithmetic model.The experimental results showed that this model could get optimal split scale expediently and fleetly,avoid the visual subjectivity,and improve the efficiency of image segmentation. |
