Digital image deblurring techniques: a comprehensive survey

Abstract

Blur in images is the most challenging issue in image processing, which is caused via multiple external factors. Deblurring is the most important process in restoring the sharpness of the original image, so many approaches and techniques were proposed. This paper covers a spectrum ofstrategies that are related to software applications for image deblurring restoration. The aim of this research is to reveal the logic behind the current algorithms and techniques in this field, helping the researchers to develop more efficient algorithms for corresponding purposes.
