Image Denoising Application Using Improved Multiscale Intensity Estimation

The Improved Multiscale Intensity Estimation method in wavelet domain presented here is a powerful new tool for image denoising and reconstruction. Specifically, we extend the so-called Multiscale Intensity Estimation in wavelet domain. Unlike traditional wavelet-shrink methods, this method is both well suited to processing Poisson data and capable of preserving image edges. At the heart of this new method lies image signal decompositions based on wavelet basis and estimation of the coefficients using the proposed estimation method. Experimental results suggest that our proposed estimation in wavelet domain can outperform standard reconstruction methods currently in use in image restoration.
