基于中值的自适应均值滤波算法

中值滤波和均值滤波通常被分别用来处理脉冲噪声和高斯噪声.但是当图像同时存在高斯噪声和脉冲噪声时,单独用那种滤波方法都不会达到最好的去噪效果.针对该问题,提出了一种基于中值的改进自适应加权均值滤波算法.该算法采用了一种基于自适应阈值的方法对滤波系数加以优化,使其可以更有效地减少噪声,又可以较好的保持图像的边缘细节信息.实验结果表明,该算法能较好的滤除混合噪声,且滤波效果优于传统的滤波算法.

Adaptive weighted average filtering algorithm based on medium value

Median filter and average filter are usually used to process impulse noise and Gaussian noise respectively.But when image is corrupted by Gaussian noise and impulse noise simultaneously,good filtering effect cannot be obtained if only using median filter or average filter.In allusion to this question,an improved adaptive weighted average filter based on the medium value is proposed.This method applies a new calculational method based on adaptive threshold to optimize coefficients of filter,and can suppress ...
