Signal decimation aimed at optimal spectral packing has a variety of applications in areas ranging from array pro cessing to image processing In this article we propose and discuss a new method for determining decimation grid and prelter that best t the spectral extension of any D signal dened on an arbitrary sampling lattice The method has been implemented and tested on digital images in order to evaluate quality degradation due to optimal spectral truncation
