| 摘 要： | 提出了一种改进的 IHS变换复合方法 ,即将小波变换与 IHS变换相结合的方法。它先将 SAR与 I进行小波融合 ,然后将融合数据代替 IHS反变换中的 I,最后进行 IHS反变换。文中对比分析了 4种复合方法 ,并且用熵、联合熵及平均梯度进行了定量评价。

| Abstract: | This paper presents a improved scheme of IHS transformation to integrate SAR and TM images, in which wavelet transform is combined with IHS transformation. First, SAR and I are fused in the wavelet transform domain, and then I is replaced by fused data, finally IHS transformation is realized in reverse. In this paper, four kinds of methods to integrate SAR and TM imges are analyzed contrastively, and evaluated quantitatively using entropy, joint entropy and average gradient. |
