An Effective Salt-and-Pepper Noise Filter
Wu Ying · Nanjing Xiaozhuang Xueyuan xuebao · 2008
Based on the extreme median filter,an improved image filter algorithm is proposed.Different algorithms are used for different noise densities.If the noise density is low,the mean filter with effective signal is used;if the noise density is high,the recursive window filter is used.Lots of experiments show that the results of salt pepper noise filtering and detail-preserving are greatly improved.
