| 摘 要： | 提出了一种IHS变换与小波变换相结合的图像融合新方法。对多光谱(TM)图像的强度分量和全色(PAN)图像分别进行小波分解，根据小波变换高低频分量的不同特点，分别采取不同的高低频融合准则形成新的小波高低频分量，再先后进行小波逆变换和IHS逆变换得到融合后的TM图像。实验结果表明，提出的图像融合算法明显改善了融合图像的客观评价和主观视觉效果。

| Abstract: | This paper proposed a new image fusion method based on the combination of IHS and wavelet transformation. The intensity component of multispectrum images(TM) and panchromatic image (PAN) was decomposed respectively by wavelet transformation. Used different fusion rules to fuse TM and PAN images according to the coefficients of low frequency and high frequency, and then obtained the fused multi-spectral image by inverse wavelet transform and inverse IHS transform respectively. The experimental results show that the fused images with the new method greatly improve the objective evaluation and subjective visual effect. |
