| 摘 要： | 针对遥感图像特征选择和提取的波段选择，利用形式概念分析中属性约简的思想设计了波段约简选择算法。该方法利用遥感影像的信息量作为指标，将多光谱影像作为形式背景，各波段作为形式属性，通过属性约简得到核心属性即最优波段，这样不仅避免了多光谱遥感数据波段之间的相关性对波段选择的影响，还提高了选取训练样本的效率。最后采用了美国地球观测卫星Landsat拍摄的TM遥感影像数据进行实验，与常用的波段选择方法相比，本文的方法更为简便和高效。

| Abstract: | In accordance with wave band selection of feature selection and extraction in remote sensing images,this paper proposes a new wave band reduction selection algorithm based on the theory of attribute reduction in concept formal analysis.This method takes information quantity of remote sensing images as index,it not only avoids the impact on band selection that causes by the correlatirion among bands of multispectrum remote sensing data,but also improves the efficiency on selecting training sample.Finally,the... |
