| 摘 要： | 以CBERS-02星全色、多光谱图像及IKONOS多光谱图像为数据源，利用离散小波变换和双树复小波变换进行融合试验。结果表明，双树复小波变换在空间细节表现力和光谱保持方面能够较好地达到平衡，较离散小波变换更能提高图像融合质量。通过融合方法对比分析可知，02B星全色波段不仅与其多光谱波段融合能够得到信息更加丰富的图像，而且与其它传感器数据融合同样有很好的目视效果和可读性，具有较大的应用前景。 |

| Abstract: | The data sources from the CBERS—02B satellite in the panchromatic band, multi-spectral band and IKONOS multi-spectra were used to perform the fusion test by DWT and DTCWT. The results show that the DTCWT could achieve a fairly good balance between the details of the space and the maintaining of the spectra, thus improving the quality of image fusion. In comparison with other fusion methods, the CBERS—02B panchromatic band can not only yield images of more information with the fusion of its multi-spectral band but also result in a good visual effect and readability with the fusion of other sensor data. The CBERS—02B satellite therefore has remarkable application prospects. |
