| 摘 要： | 本文针对多光谱图象的增强问题，提出了一种基于小波变换理论的融合增强方法。它将高空间分辨率的全色图象和多光谱图象经小波变换后的低频分量进行融合，改进了传统基于小波变换理论的增强方法。本文还对比评价了基于IHS变换和传统小波变换的增强结果，表明了该方法在提高多光谱图象的空间细节表现能力和保持地物光谱信息上都具 有很好的效果。 |

| Abstract: | A method based on wavelet transform is described to enhance a multispectral image by merging with a relatively high spatial resolution image This method improves a standard wavelet merger for merging the lower frequency coponents of a multispectral image and its relatively high spatial resolution image Compared with the IHS and standard wavelet mergers,the new method presented is clearly better in preserving spectral and improving spatial presentation |
| Keywords: | multispectral image data fusion wavelet transform image enhancement |
