Abstract
Two methods tor digital restoration of pictures blurred by imperfections of the optical system and by random noise are suggested. Method one is based on the a priori information that a picture has nonnegative intensity and leads to quadratic programming. In method two, the finite extent of the picture is shown to make Fourier transformation in the complex domain useful.
