Adaptive image denoising method based on wavelet transform and ridgelet transform
基于小波变换和脊波变换的自适应图像去噪算法

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.
