Abstract

To reduce boundary artifacts in image deblurring, we propose the normalized backprojector, as a replacement of the standard backprojector. The proposed normalized backprojector is designed to compensate for non-uniformity of contributions of image pixels to the observation. Simulation studies in this paper showed that the simple replacement of the standard backprojector with the normalized one reduced boundary artifacts efficiently.
