摘要

提出一种结合离散余弦变换（DCT）与GIHS变换的遥感影像融合方法。该方法根据DCT的性质直接在DCT域进行遥感图像融合

适合于实时系统。对现有算法的融合实验结果进行比较

通过主观和客观评价

该方法能在提高空间分辨率与保持光谱特性之间得到更好的折中。

Abstract

A remote sensing image fusion method which combines discrete cosine transform（ DCT） and GIHS transform is proposed. The proposed approaches can be applied in DCT domain for remote sensing image fusion according to DCT transform features

it is suitable for real-time system. Compared with fusion experiment result of existing algorithm

through subjective and objective evaluation

this method can obtain better tradeoff between improving spatial resolution and preserving spectral characteristics.
