说明：  基于快速离散曲波变换的图像去噪算法，该方法可以消除由于Curvelet变换缺乏平移 不变性而产生的图像失真，并且更好地利用曲波系数的相关性。
(Fast discrete curvelet transform based image denoising algorithm, the method can eliminate the lack of translation invariance Curvelet transform arising from image distortion, and better use of the curvelet coefficients of correlation.)
