针对图像融合难以选择合适的评价指标的问题，通过分析主观评价与客观评价指标之间的相关性，提出一种合成评价指标方法对多波段图像融合结果进行评价。首先，从边缘清晰度、自然感、信息量及综合评价四个方面对多种方法融合结果进行主观评价；其次，用14种常用的客观评价指标对融合结果进行评价；然后，对主客观评价结果分别归一化，并采用斯皮尔曼(Spearman)相关系数分析每种客观评价指标和四种主观评价之间的相关性；最后，根据该相关性分别从四个评价方面，用14种客观指标合成一种综合指标。实验结果表明，综合指标与主观评价的相关性比单项指标或其他合成指标更高。

It is difficult to select an appropriate evaluation index for current image fusion. In order to solve the problem, a synthesis evaluation index is proposed based on the correlation between subjective and objective evaluations. First, a variety of fusion results are evaluated subjectively from the edge of clarity, natural sense, in-formation and comprehensive evaluation, respectively. Secondly, 14 commonly objective indexes are used to evaluate the fusion results. Then, the subjective and objective results are normalized, and the Spearman correla-tion coefficient is used to analyze the correlation between the four subjective evaluations and each objective evaluation. Finally, according to the correlation, a comprehensive index is constructed through 14 objective in-dexes in 4 aspects. The experimental results show that the synthesis index is more relevant to subjective evalua-tion than the individual evaluation index and any other comprehensive indexes.
