Abstract:
Objective: Several denoising methods for medical images have been applied, such as
Wavelet Transform, CNN, linear and Non-linear methods.
Methods: In this paper, A median filter algorithm will be modified and the image denoising
method to wavelet transform and Non-local means (NLM), deep convolutional neural network (Dn-
CNN), Gaussian noise, and Salt and pepper noise used in the medical image is explained.
Results: PSNR values of the CNN method are higher and showed better results than different filters
(Adaptive Wiener filter, Median filter, and Adaptive Median filter, Wiener filter).
Conclusion: Denoising methods performance with indices SSIM, PSNR, and MSE have been tested,
and the results of simulation image denoising are also presented in this article.
