摘要
随着高空间分辨率、相对低光谱分辨率的新型遥感图像的出现和普及,基于像元、依赖于光谱信息特征的传统遥感分类方法已不能很好地适应新型数据的分类工作。通过应用面向对象的多层次分割分类方法对广东省黑石顶自然保护区的QuickBird遥感图像进行了分类尝试。分类结果显示相对于传统的基于像元的分类方法,基于对象的多层次方法具有更准确的分类结果、更明确的分类边界和更均一的内部同质性。
With emerging and prevailing of the new remote sensing images that have traditional classification methods based on pixels and spectral information of images has been not adapted to new data. Using the method of object-oriented and multi-level segmentation technique, This paper classified QuickBird remote sensing images of Heishiding Nature Reserve in Guangdong Province. The results showed that compared to traditional pixel-based classification methods,multi-level classification method based on objects can get the more accurate classification results, the more clearly classification boundary and the more uniform internal homogeneity.
