摘　　要：基于三角模融合算子的混合滤波算法运用三角模算子对边界点进行融合判断,从而运用融合结果,进行混合滤波,该算法在一定程度上改善了单纯的混合滤波器的性能.但该滤波器,只是运用融合技术对图像边界点进行判决,在像元点的处理上还是采用单一的或是线性或是非线性滤波技术,存在着其不可避免的缺陷.为此,本文提出了一种基于改进型的三角模准则的融合滤波算法,本文算法真正将融合理论运用到滤波技术中,提高了滤波效果.后续仿真实验证明了本文算法的有效性,为图像滤波的技术发展提供了一个新的探索途径.Hybrid filtering algorithm based on triangle modulus operator makes fusion decision about the boundary point,and performs hybrid filtering based on the fusion results.Accordingly,this algorithm improves performance of hybrid filter.However,there is an inevitable shortcoming in this hybrid filtering algorithm,which implements filtering at pixel domain only with single liner or nonlinear filtering,while it makes fusion decision about the boundary point.In this paper,in order to overcome the shortcoming,a new fusion filter algorithm based on triangle modulus fusion operator was proposed.The proposed algorithm improves filter performance with information fusion.The experiment results show the validity of this new algorithm.Moreover,the proposed algorithm provides a novel approach to image filter technology.
