摘要

A quantitative metric was proposed to objectively evaluate the quality of fused images. First, the Fuzzy C-Means clustering algorithm (FCM) was used to segment image in order to obtain the regional feature matrix. After dimensionality reduction, we could calculate the distance between regions as regional similarity. Secondly, we used the ratio of the principal eigenvector derived from two original corresponding image regions as the weight of corresponding regions. The ratio of edge vectors amplitude between regions was used to denote local region saliency. Finally, we could attain the similarity between images. The results show that the proposed metric is more consistent with the human perception nature as it considers the local image variations and the regional saliency.
