In response to the flaw that the median filtering algorithm has a poor handling capacity to high-density and fine texture noise

noise detection-based adaptive median filter algorithmis proposed. According to the associated level between noise-point information and the surrounding

the new algorithm adjust the Noise point filter value

which can get a better deal with the details of the images. The adaptive strategies strengthen the performance of the filtering de-noising algorithm

which is good at dealing the high-density noise. Through simulation analysis

the new algorithm is better than other algorithms.
