A new method for image de-noising which colligated the strongpoint of Contourlet transform and Recursive Cycle Spinning was presented.Due to the lack of translation invariance of the Contourlet transform
image de-noising by coefficient thresholding would lead to Gibbs-like phenomena(lead to artifacts).Recursive Cycle Spinning was employed to avoid the artifacts.The experimental results indicate that the method can get better visual effect and PSNR value compared with the methods like wavelet image de-noising using the Recursive Cycle Spinning.
