Webbthe method may converge slowly. Subsequently, we describe an iterative active set method that imposes the same constraints on the computed solution as the Richardson-Lucy method. Computed examples show the latter method to yield bet-ter restorations than the Richardson-Lucy method and typically require less compu-tational eﬀort. 1.
