  • Abstract
    Optimal threshold selection for multiwavelet denoising using multivariate shrinkage is considered. Unlike other risk estimators which are derived for a single threshold, a new risk estimator is proposed for each decomposition level based on the principle of Stein´s unbiased risk estimator.
