Abstract :
In order to avoid the effect of Pseudo-Gibbs phenomena, Cycle-Spinning, used in the image de-noising, was produced in this background. With the thought of cyclic shift, this paper considers the relationship among each step of the whole reconstruction process, studies the involved inverse translation and the average operation, and proposes two different reconstruction methods. The experimental results indicate these methods can eliminate the Pseudo-Gibbs phenomenon, and get better visual effects subjectively and higher PSNR value objectively.
