Image Denoising Using Shearlet Transform and Nonlinear Diffusion
Xiaobo Zhang · 2015
In this paper, we present a new image denoising method for removing Gaussian noise from corrupted image by using shearlet transform and nonlinear diffusion.The image is decomposed by the shearlet transform to obtain the shearlet coefficients in each subband; then a diffusion scheme based on statistical property of shearlet coefficients is used to shrink noisy shearlet coefficients.The test shows the proposed method has better performance compared to the relevant methods.
