A novel fusion filtering algorithm is proposed to resolve the problems of the hybrid filtering algorithm based on advanced D-S theory of evidence. The hybrid filtering algorithm judge image edges. However, for the image pixel, the hybrid filtering algorithm adopts the single method that is linear or non-linear, and it is not a real fusion filtering algorithm. Accordingly, the proposed algorithm based on fusion theory judges image edges, but also makes fusion filtering, which improves the performance of filtering. The experimental results indicate that the proposed algorithm is effective.
