Abstract [English] The present invention describes methods and techniques to improve scintigraphic images obtained by using nuclear medicine techniques for diagnostic analysis. The present invention describes a method and technique to up-sample and down-sample nuclear medicine images that models photon counts and noise characteristics of an image at its target resolution. [French] La présente invention concerne des procédés et des techniques permettant d'améliorer des images scintigraphiques obtenues à l'aide de techniques de médecine nucléaire pour une analyse diagnostique. La présente invention concerne un procédé et une technique permettant de suréchantillonner et de sous-échantillonner des images de médecine nucléaire qui modélisent des comptages de photons et des caractéristiques de bruit d'une image à sa résolution cible.
