面向对象信息提取的共性技术研究

面向对象的信息提取方法已成为高分辨率遥感影像信息提取研究的热点,许多学者利用该方法对遥感影像进行分类和信息提取,并取得了很好的效果。但目前还没有人对其共性技术进行系统的总结。本文总结了面向对象的遥感影像信息提取通用技术流程,并对其中的共性技术如影像分割、特征定义及选取、影像分类等做以相关的介绍。

The Common Technologies of Object-based Information Extraction

The method of object-based information extraction has become a research hotspot for high-resolution remote sensing image.Many scholars make use of the method of remote sensing image classification and information extraction,and has good results.There has been no common technology for its system summary systematic summary.In the paper,the common process and technologies of object-based information extraction is summed up and common technologies,such as image segmentation,feature definition and selection,image classification are introduced.
