摘要
分析了的Brovey变换融合算法,提出了一种新的基于Brovey变换、对数变换亮度调整的图像融合方法,试验数据的对比和分析证明了其保留多光谱影像的光谱信息。
A new image fusion method is proposed on the basis of combining Brovey transform with logarithmic transformation for intensity modulation. Experimentatl results proveds that this improvement of ordinary Brovey transform keeps higher resolution ratio and better spectrum character.
