Abstract

This paper mainly focuses on the development of using wavelet coefficients' intra scale dependency of natural images. Wavelet transform (WT) coefficients have statistical dependency. WT coefficients have dependency between local coefficients (intra-scale). This paper uses dependency between children's coefficient for estimating corrupted by noise. For this purpose, we derive the bivariate model using correlation between coefficients and shrinkage function for denoising.
