Aravind B.N., K. V. Suresh . Two-step Image Denoising. Communications on Applied Electronics. 4, 2 ( January 2016), 1-5. DOI=10.5120/cae2016652054
Image denoising is an area of active research. Many image denoising techniques have been proposed in literature both in spatial and transform domain. Image denoising always strikes a balance between noise removal and preserving edge information. An improved two-step approach using stationary wavelet transform is proposed in this paper. The first-step uses neighshrinksure followed by the nonlocal means method for denoising. The simulation results on synthetic and real images demonstrates the improvement of the proposed method.
