Abstract
A relationship is shown between the usual formulation of constrained iterative restoration and restoration by successive projections onto convex sets. When used with a reasonable convergence criterion, this relationship characterizes the restoration as the point closest to the initial estimate which satisfies the convergence criterion. Experimental work is presented to demonstrate the effects of the choice of the initial estimate.
