摘要：
A new method of image denoising was put forward, based on integrated utilization of Curvelet transform and Cycle spinning. Because there existed "encircling" phenomenon for Curvelet transform, if images threshold denoising of Curvelet coefficients was performed directly, the image would be distorted, in this paper, Cycle spinning was introduced to eliminate the image distortion produced by "encircling". The simulation experiment indicated that the algorithm had perfect inhibiting ability for noise, moreover, it can protect the detail information of image; when different kinds of impulse noise images with different density were filtered, satisfied results can always be obtained.
