Scintigraphic image denoising using Fisz transformation and redundant wavelet packets
Nawrès Khlifa, Kamel Hamrouni, Noureddine Ellouze · 2005
Image denoising by wavelet coefficients thresholding is an approach in full evolution considering the growing number of publications, which are interested in this methodology of filtering. In this paper, we propose a new method of denoising scintigraphic images based on redundant wavelet packet decomposition (using a modified version of Bayes’s threshold) and Fisz transformation to transform the poissonnian noise in a Gaussian one. In collaboration with physicians of nuclear medicine, results are considered important.
