利用傅立叶变换和CIELab变换的FFT-LAB方法研究

Study on Remotely Sensed Image Fusion Method Based on FFT and CIELab Transform

摘要: 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。

Abstract: 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.
