摘要 提出了基于小波变换的ETM+影像可调节融合方法。该方法引入可调节参数,将ETM+影像在小波域内进行融合,从而使得融合
影像在光谱保持能力和高分辨率保留能力之间达到不同程度的平衡。实验结果表明,在某些参数组合下, 可以得到单独使用某种传
统融合法所不能达到的目视效果和统计指标。

Abstract : In this paper, a new ETM+ image controllable fusion method based on wavelet transform is proposed. By
introducing parameters, these ETM+ image were fused in wavelet space and the balance between preservation of
spectral characteristics and retention of high spatial resolution can be achieved at different levels.
Experimental results show that, with the combination of some parameters, the visual effects and the statistic
indices that traditional image fusion methods fail to achieve can be attained by using the method proposed in this
paper.
