摘要
以非下采样(Contourlet)变换为基础,提出了一种新的图像去噪方法,首先对含噪图像进行非下采样轮廓变换,然后采用自适应阈值对变换系数进行处理,最后重构回原图像。
Based on the non-sampling (under) eontourlet transformation, this paper proposes a new image denoising method. At first it makes non-sampling contourlet transformation for the noise image, and then uses self-adaptive threshold to process the transform coefficient, finally back to the original image reconstruction.
