According to shortcoming of conventional median filter algorithm in filtering salt and peper noise of image,the essay brought up a way of an adaptive switching interpolation filter.This method checked and identified noise through maximum-minimum and block uniformity,and then according to the distributed noise,filtered noise by using Lagrange interpolation and adaptive median filter.Experiment results on images with noise densities from 10% to 80% show that the proposed filter performs well in reducing salt and pepper noise and maintains a good image detail information.Therefore it has better filtering performance than the conventional median filter algorithm,and it provides a new way for image denoising.
