一种新的基于目标检测的波段选择方法

针对现有的高光谱遥感波段选择方法应用于目标检测时效果不高的问题，提出了基于目标检测的波段选择方法两步波段选择（Two Step Band Selection，TSBS）方法。该方法首先应用典型波段选择方法对高光谱波段进行初选；然后根据波段逐一累积后不同波段组合的目标检测效果，对初选波段进行再次选择，最终得到目标检测效果更好的波段组合。该方法不仅继承了典型波段选择方法的优点，而且直接基于目标检测的效果选择波段，应用针对性强，方法简单易行。实验结果表明:TSBS方法在高光谱数据波段选择方面具有较好的普适性，能够在实现数据降维的同时，有效改善目标检测的效果。

Novel band selection method based on target detection

To solve the problem of not good enough target detection results while applying present hyperspectral remote sensing band selection methods, a novel band selection method based on target detection-Two Step Band Selection(TSBS) was proposed. Primarily, hyperspectral bands were initially selected and sorted via typical band selection method. Then according to the target detection results of different band subsets after successively accumulating each band, the initially selected bands were reselected again. Finally, the band subset with better target detection result was obtained. The proposed method could not only inherit the advantages of typical methods, but also had higher application pertinence and simple implementation due to its direct target detection-based band selection. Experimental results show that TSBS method has better general applicability. Both hyperspectral data dimensionality reduction and improvement of target detection result can be realized effectively.
