For defects of image filtering algorithm based on the modified Information entropy (IIE), a novel fusion image filtering algorithm based on edge point judgment by fusion entropy is proposed in this paper. IIE algorithm only fuses the decision of edge point and it still uses single method (linear or nonlinear filters) for image pixel. So it is not a real fusion filtering algorithm. Therefore, the proposed algorithm not only applies fusion theory to edge point judgment, but also uses fusion theory for fusion filtering which can improve the performance of filtering. The experimental results indicate that the proposed algorithm is effective.
