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.
