The contribution of this paper is to develop and analyze a new wavelet-based regularized restoration method for noise removal in photon limited imagery. This new framework presents the two main following advantages: (1) it assigns a new value to the non-significant wavelet coefficients which reduces artifacts and enables the incorporation of realistic prior information into the estimation process and (2) it is based on a local detection process with a measure of the significance of the detected structures. Its potential to improve nuclear medicine imaging is examined.
