Abstract

An evaluation model of image fusion based on entropy weight method is put forward to resolve evaluation issue for fused results of multispectral and panchromatic images, such as the lack of overall importance in single factor metric evaluation and the discrepancy among different categories of characteristic evaluation. In this way, several single factor metrics in different aspects of image are selected to form a metric set, then the entropy weights for each single factor index are calculated based on entropy weight method, thus a new comprehensive evaluation index is obtained to evaluate each fused image and images with higher spectral resolution and spatial resolution can be acquired. Experimental analysis shows that the proposed method is of versatility, objectivity and rationality and performs well on the evaluation of fused results of multispectral and panchromatic images.
