一、引言遥感影像的自动解译一直是研究的热点,也是难点。目前,主流的遥感影像处理软件如eCognition(易康)、ERDAS、ENVI都能够提供遥感影像自动解译功能。其中eCognition是由德国Definiens Imaging公司开发的智能化影像分析软件,提供面向对象的遥感信息提取功能,具有独特的多尺度分割技术。遥感影像的自动解译包括分割和分类两个步骤,其中分割是分类的基础,分割的好坏决定着分
I. INTRODUCTION Automatic interpretation of remote sensing images has always been a hot topic and a difficult one. At present, mainstream remote sensing image processing software such as eCognition, ERDAS and ENVI can provide automatic interpretation of remote sensing images. Among them, eCognition is an intelligent image analysis software developed by Definiens Imaging in Germany. It provides object-oriented remote sensing information extraction and unique multi-scale segmentation technology. The automatic interpretation of remote sensing images includes two steps of segmentation and classification, in which segmentation is the basis of classification.
