The problem of estimating a signal that is corrupted by additive noise has been of interest to many researchers for practical as well as theoretical reasons. Many of the traditional denoising methods have been using methods such as the Wiener filtering. Recently, nonlinear methods, especially those based on wavelets have become increasingly popular, due to a number of advantages over the linear methods. It has been shown that wavelet and multiwavelet thresholding guarantees better rate of convergence, despite its simplicity. This paper demonstrates the work of combining Parametric multiwavelet and Sureshrink to remove noise from the signal. Experimental results shows that the proposed work is 4% efficient in terms of SNR values and image quality when compared to other wavelet families
