基于小波变换和脊波变换的自适应图像去噪算法

为了克服单纯小波变换或脊波变换的不足,提出了基于小波变换和脊波变换的自适应去噪算法。实验结果表明,在处理点奇异性和线奇异性的图像时,该方法比单纯小波变换或脊波变换的阈值去噪算法更具优越性,在实际应用中更为有效。

Adaptive image denoising method based on wavelet transform and ridgelet transform

In order to overcome the shortages of the wavelet and ridgelet transform, this paper proposed an adaptive image denoising method based on wavelet transform and ridgelet transform. The experimental results show that, while processing point and line singularities in an image, this adaptive method has significantly superiority over the threshold denoising algorithm only based on the wavelet transform or ridgelet transform. This novel algorithm is more powerful in practice.
