    A Based Bayesian Wavelet Thresholding Method to Enhance Nuclear Imaging by Nawrès Khlifa, Najla Gribaa, Imen Mbazaa, Kamel Hamruoni

    Published 2009-01-01
    “…Since these images are modeled as the realization of a Poisson process, we propose a new framework that performs variance stabilizing of the Poisson process before applying an adapted Bayesian wavelet shrinkage. The proposed method has been applied on real images, and it has proved its performance.…”
