The verification model of multi-focus image fusion by simulating subjective evaluation

Abstract

We present a model to simulate the subjective evaluation and compare various fusion algorithms. First, we produce an all-focus image and two multi-focus images by the help of two filters. Second, we fuse two multi-focus images with two representative algorithms WT and CT. Third, we decide the optimal fusion rules of WT and CT by comparing the fused images with an all-focus image. Finally, we improve the performances of fused images by combining several algorithms. Simulation shows the verification model can compare various fusion algorithms or rules. Meanwhile, our fusion model can get better performances than other algorithms or rules.
