VisuShrink, ModineighShrink and NeighShrink are efficient image denoising algorithms based on the discrete wavelet transform (DWT). These methods have disadvantage of using a suboptimal universal threshold and identical neighbouring window size in all wavelet subbands. In this paper, an improved method is proposed, that determines a threshold as well as neighbouring window size for every subband using its lengths. Our experimental results illustrate that the proposed approach is better than the…

TLDR
This paper extends the idea of Cai and Silverman for developing a new image denoising method and determine the coefficients of neighboring window for every subband and shows that in most of the cases, the proposed method performs better than the NeighRink, ModiNeighShrink, and IIDMWT in terms of peak signal- to-noise ratio and structural similarity index measure.
