通过高光谱遥感图像空间邻域内光谱特征的变化,研究了邻域光谱度量指数;根据邻域内端元光谱特征的变化,提出了邻域独立端元指数提取图像的空间维细节信息。通过真实高光谱遥感图像检验,两类邻域指数能够较好地提取高光谱遥感图像中的细节,为进一步结合空间维、光谱维特征的高精度目标探测与识别创造了有利条件。 更多还原

【Abstract】 Hyperspectral remote sensing image provides not only abundant spectral information but also spatial detailed infor-mation.For making full use of the information,this paper considered the variations of the spectral feature among pixels in local neighborhood and researched on a kind of Local Neighborhood Spectral Similarity Measure Index to extract the spatial detailed information.Furthermore,the spectral feature of endmember in local neighborhood was also considered.And a kind of Local Neighborho... 更多还原
