| 摘 要： | 以南京市部分主城区为研究对象，首先利用基于多尺度图像分割方法对图像进行分割； 然后利用对象所包含的光谱、形状及纹理等特征确定地物识别中所需的各种特征参数； 最后，通过规则的建立，实现研究区地物的逐级分层分类。研究结果表明，该方法不仅使分类结果具有丰富的语义规则信息，而且还有效减少了“分类椒盐现象”的产生，分类精度显著提高。

| Abstract: | With the main city zones as the research area, this paper studied the method for extracting water information in SPOT 5 image. First, the image is segmented by multi -segmentation methods. After that, in combination with some spectral, shape and textural characteristics, the multi -level classification method can be set up. The result shows that this kind of classification method used to extract the water information in city zones has not only abundant rules -meaning information that can reduce the salt- phenomenon but also obviously high accuracy. |
