| 摘 要： | 针对遥感图像波段选择传统手工方法的不足，应用粗糙集理论，从纹理分析的多个角度选择特征，多方面挖掘数据的关键属性；通过核属性时方法计算达到简化决策表中的条件属性的目的，得到图像分类的关键波段和一些次关键波段；实现了波段的自动选择．该算法比传统方法更客观更简便，为遥感图像波段选择提供了崭新的方法．

| Abstract: | In this paper, the method of getting optimal bands from remote sensing image is discussed. Firstly, by analyzing the features of texture, it gets some key attributes of data at multi - aspects. Secondly, according to the method of calculating the core, condition attributes of decision table are reduced. Finally, optimal bands and some sub - optimal bands are gotten. By this way it can overcome the defect of traditional method which gets the result by hand. The algorithms is objective and simple, it provides a new approach to bands selection. |
