| 摘 要： | 针对CT变换缺少平移不变性会在图像消噪时产生伪Gibbs现象,提出了非下采样CT变换与自适应阈值法相结合的图像消噪法。实验结果表明,采用非下采样CT变换方法能有效地消除图像噪声,保存图像的纹理细节,提升图像信噪比,消噪效果优于传统小波及CT消噪效果。

| Abstract: | The author of this paper proposes an image de-noising method of non-subsampled CT transform combined with adaptive threshold to deal with the phenomenon that the lack of transla-tion invariance of CT transform can produce pseudo Gibbs in image denoising.Experiments show that the non-subsampled CT transform method can eliminate noise effectively,preserve image texture details,improve the image SNR,and that de-noising effect is better than that of tradi-tional CT and wavelet. |
