Abstract
This paper presents a new filtering algorithm using multi-threshold decomposition filter (MTDF) to solve the contradiction between impulse noise attenuation and image detail-preserving. The algorithm firstly uses Otsu’s threshold segmentation (OTS) to segment the image into four parts by steps. Then the matrices of the impulse noise location can be obtained respectively using the threshold decomposition multistage median filter (TDMMF). At last, median filters separately according to the matrices filter the noise pixels in the original image. The results indicate that the method has not only the good ability of de-noising but also better properties in preserving details than median filtering.
