| 摘 要： | 在已有极值中值的滤波算法的基础上,提出一种自适应滤波算法.该算法对于不同椒盐噪声密度采用不同滤波方法,在噪声密度较低时,采用同时考虑灰度差值和空间距离的自适应权重函数进行滤波,在噪声密度较大时,采用递归方式进行均值滤波.实验证明,该算法在滤除椒盐噪声能力、细节保护能力方面均有较大提高.

| Abstract: | Based on the extremum median filter,an auto-adaptive image filtering algorithm is proposed.Different algorithms are used for different noise densities.If the noise density is low,an auto-adaptive weight filter can be used based on both amplitude and spatial position.If the noise density is high,the image can be filtered by the recursive mean filter.It has been found in the experiments that the results of salt & pepper noise filtering and detail-preserving are greatly improved. |
