  • Abstract
    The classical wavelet denoising scheme estimates the noise level in the wavelet domain using only the upper detail subband. In this paper, we present a hybrid method for wavelet image denoising in which the standard deviation of the noise is estimated on the entire image pixels in the spatial domain within an adaptive edge preservation scheme. Thereafter, that estimation is used to calculate the threshold for wavelet coefficients shrinkage.
