结合CIELab颜色空间和傅立叶变换的优点,提出了基于傅立叶变换和CIELab变换的多源遥感影像融合方法——FFT—LAB。实验表明,该方法优于目前的GS、PCS、Pansharp等融合方法。
A fusion method, which is called FFT-LAB and based on Fast Fourier transform and CIELab transform, is put moposed to fuse panchromatic and spectral images. Emperimental results on images of IKONOS demonstrate that the performance of FFT-LAB is better than that of Gram-Schmidt Spectral Sharpening(GS),PCS, and Pansharp.
