Scientific paper

We apply a total variation minimization technique for the deblurring of 2D images. This yields an integro-differential equation with a nonlinear elliptic partial differential operator. In this paper we discuss a numerical scheme for the efficient solution of this integro-differential equation. Results are presented for a doconvolusion problem arising in ground-based astronomical imaging.
