geometric simplex

用法例句

The simplex-based methods are most important and widely used methods for the decomposition of mixed pixels in multispectral and hyperspectral remote sensing images,which need a strong basic hypothesis that there is at least one pure pixel for every end-member existing in the images.

单形体几何学方法是混合像元分解中一类重要的方法,这类方法均需要一个较强的前提假设,即每一端元在图像中均至少存在一个纯像元。
