PERFORMANCE ASSESSMENT OF COMBINATIVE PIXEL-LEVEL IMAGE FUSION BASED ON AN ABSOLUTE FEATURE MEASUREMENT

Abstract

Abstract. In this paper, a new metric for evaluating the performance of the combinative 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.
