摘要
本文采用四种典型的ＩＨＳ变换对同一地区的ＳＡＲ与ＴＭ影像进行了复合，并对复合影像作了定性和定量的分析。试验结果表明：用熵、联合熵和平均梯度这３个客观定量指标评价复合效果不仅比目视评价准确有效，而且提供了选择最佳ＩＨＳ变换用于复合的方法。
In this paper, four kinds of IHS transformations are used to integrate SAR and TM images. The resultant images are evaluated qualitatively and quantitatively. It shows that the quantitative analysis using entropy, joint entropy and average gradient is better than visual quantitative analysis, and provides the way to choose the most suitable IHS transformation for combining images.
