Abstract

There exist various image de-noising techniques. Amongst them orthogonal wavelet is preferred one. However, the orthogonal wavelet transform is not better technique as proper clustering of wavelet coefficients is not possible in this technique. So a better image de-noising technique is needed to have a better SNR and greater image information. In this work, image de-noising by linear minimum mean square-error estimation (LMMSE) scheme is proposed and results show that this method outperforms some of the existing de-noising techniques.
