Abstract :
Two methods for recovering an image that has been degraded while being processed are presented. The first algorithm reduces the problem to the computation of a few discrete Fourier transforms. The second algorithm with weight matrices included enables the handling of edges and flat regions in the image in a pleasing manner for the human visual system. These algorithms have been applied to nuclear medicine images
