军事目标光谱提取的有效性分析

Effectiveness Analysis for Military Target Spectrum Extraction

为研究光谱提取方法对军事目标的有效性,用三种典型方法对含军事目标的高光谱图像进行了端元提取。结果表明,只有基于纯像元指数的端元提取方法能够有效地提取到军事目标的光谱,而基于散点图的端元提取方法以及SMACC方法都提取不到军事目标。对光谱提取结果的深入分析表明,军事伪装技术措施、军事目标的尺度和数量是影响光谱提取有效性的重要因素。在此基础上,提出了提高军事目标光谱提取有效性的技术途径。

For the purpose of investigating the effectiveness of different methods for military target spectrum extraction,end member extraction was carried out with three typical methods for a hyperspectral image.It was found that only based on pure pixel index was effective,whereas military target spectrum could not be extracted by the extraction method based on scatter diagrams and SMACC method.As the research results were profoundly analyzed,camouflage method,small size and small number of military targets were thought to be the reasons for the ineffectiveness.With the basis of this,some strengthened methods were put forward to increase the effectiveness.
