This strategy can catch richer interscale correlation of the contourlet coefficient, and then is more suitable for representing non-Gaussian statistics and ...
In this paper, a denoising algorithm based on contourlet transform for the OCT heart tube image is proposed. A bivariate function is constructed to model ...
This paper proposes a new image denoising method in the contourlet domain by using the alpha-stable family of distributions as a prior for contourlet image ...
The contourlet transform can very well capture the directional geometrical structures of natural images. In this paper, by incorporating the ideas of ...
The experimental results show that the improved DenseNet has better performance no matter compared with BM3D, which is recognized as the best denoising ...
In this paper, we propose an adaptive multiple steps local Wiener filter image denoising algorithm in the wavelet domain. This algorithm can be considered ...
