小波是建立在泛函分析、调和分析、傅立叶分析基础上的时频原子,在时域、频域同时具有良好的局部化特性和多分辨率特性。遥感影像融合是遥感影像处理中的重要环节,是人们处理多源遥感影像数据的主要手段之一,而融合方法的选择对融合结果来说至关重要。将传统的融合方法与小波结合已经成为研究的热点,本文将小波变换与HIS融合方法相结合,并通过实验证明该方法能够在提高空间分辨率的同时很好的保持多光谱影像的光谱信息。%Wavelet is a kind of atom about time frequency on the base of functional analysis,harmonic analysis and Fourier＇s analysis.It simultaneously has the sectional characteristic and the multi-resolution characteristic in the time and the frequency domain.The remote sensing image fusion is an important link in the remote sensing image processing,is an important method of image data processing.But the method choice is the key to fusion result.the recent years,union the traditional fusion method and the wavelet has become the research focus.This article combined the wavelet and the HIS transformation fusion method,and experiments proved this method can maintain the spectrum information of multi-spectrum image and the high resolution of the pan-image at the same time.
