A new method for image de-noising which colligated the strong point of Contourlet transform and the magnitude of the detail of image in every scale and direction.This paper deals with the problem of snuffing out the Contourlet coefficients to exceed,and it also can solve the problem of taking no consideration of image details.Experiment on image de-noising shows that:compare to the wavelet threshold,Contourlet threshold and multi-scale threshold using Contourlet transform,the two methods both pick up the im...
