Abstract
We explore utilization of seven different potential functions in restoration of images degraded by both noise and blur. Spectral Projected Gradient method confirms its excellent performance in terms of speed and flexibility for optimization of complex energy functions. Results obtained on images affected by different levels of Gaussian noise and different sizes of the Point Spread Functions, are presented. The Huber potential function demonstrates outstanding performance.
