%X A nonlinear multiscale pyramidal decomposition based on median transform is presented in this paper at first.Then it gives a denoising algorithm which can restore the image distorted by impulse noise and Gaussian noise.The coefficients of the image via the median pyramidal transform represent different characteristics, so the transform can effectively detach noise from image. The different noise coefficients suppression means can be adopted to remove different noise. The simulation result indicates the method is effective, and superior over other methods.
