Dans cet article on utilise la méthode de projection sur les ensembles convexes (appellé FOCS) pour rétablir les images à partir de l'information incomplète. La methode POCS est equivalent à trouver un point de l'intersection de m ensembles convexes, où m est le nombre de propriétes de l'image connues à priori. On démontre comment la méthode POCS est utilisée pour retablir les images a partir de 1. l'information incomplète dans l'espace de Fourier et 2. l'information dans l'espace de phase suelement
