细节增强 meaning in English

detail enhancement

However , for most remote sensing image fusion , the requirements of spectral preservation and spatial characteristics enhancement are usually incompatible . it is hard to satisfy these two requirements only by single fusion method
然而,大多数遥感图像融合存在光谱信息保留和空间细节增强的不一致性,只凭单一的融合方法,很难满足光谱信息保留和空间细节增强两方面的应用要求。
It can not only enhances the spatial detail features of result image greatly , but also preserves more spectral characteristics from original multispectral images , and fulfills the unification of spatial details enhancement and spectral information preservation effectively
它既能较好地增强融合结果图像的空间细节特征,又能保持较多的原始多谱图像的光谱特性,实现了空间细节增强和光谱信息保留的有效统一。
