查询词典 polarizing angle

By fusing the IKONOS multi-band and pan image using several image fusion algorithms(IHS transform, PC transform, Gram-Schmidt transform and smoothing filter-based intensity modulation) and assessing the fusion image, indicates that qualitative comparison is too subjective, although many methods are provided for assessment when using quantitative methods, more bands and more methods should be used for their limitations, spectral curve comparison was the best method for appraising the result, spectral angle and geometry distance was introduced to appraise the spectral curve.

以IKONOS影像为数据源，对IHS、PC，Gram-Schmidt和基于亮度调节的平滑滤波四种融合算法进行融合处理，对其结果进行了评价。结果表明，定性比较主观性较强，定量比较方法虽多，但大都有一定的局限性，不同谱段的计算结果总有些差异。因此，定量评价时应该多选一些波段与评价方法才能获得比较客观的评价结果。光谱曲线的比较不失为一种比较好的方法，在对光谱曲线进行比较时本文引入了光谱角度和几何距离两种方法进行定量的比较。
