| 摘 要： | 以高分辨率遥感影像为数据源,采用面向对象的影像分析软件eCognition提取水体。首先采用多尺度分割算法生成对象,然后对影像中水体的特征进行分析,最后建立对象知识库进行细分类。实验表明,相对于传统方法,面向对象方法能够得到更好的效果。

| Abstract: | This paper take High resolution remote sensing image as data source,combine with object-oriented methods,an object-oriented method to extract water is put forward.First,using Multi-scale segmentation algorithm to generate objects,and then analysis the characteristics of the water in the image,at last establish the knowledge base of object to subdivision.Experiments show that compared with traditional methods,object-oriented method can obtain better results. |
