本文基于图像特征度量，即相位一致性及其矩，定义了一种新的评价像素级图像融合性能的度量方法，它提供了图像特征的绝对度量。通过比较输入图像和融合输出图像的局部互相关性，在没有参考的情况下对融合结果的质量进行评估。多聚焦图像对上的实验结果表明了该方法的有效性。关键词：图像融合，相位一致性，特征度量
In this paper, a new metric for evaluating the performance of the combi- native pixel-level image fusion is defined based on an image feature measurement, i.e. phase congruency and its moments, which provide an absolute measurement of image features. By comparing the local cross-correlation of corresponding feature maps of input images and fused output, the quality of the fused result is assessed without a reference. The experimental results on multi-focused image pairs demonstrate the efficiency of the proposed approach. Keywords: Image fusion, Phase congruency, Feature measurement
