A Survey on Digital Image Restoration

Digital image restoration is a field of engineering that deals with methods used to recover an original scene from degraded observations. The goal of this article is to introduce digital image restoration to the reader, who is just beginning in this field, and to provide a review and analysis for the reader who may already be familiar in image restoration. The perspective on the topic offered here is to let the readers to know various methods of digital image restoration. It should be noted, however, that digital image restoration is a very broad field, as we will discuss, and thus contains many other triumphant approaches that have been developed from different perspectives, such as optics, astronomy, and medical imaging. In the process of reviewing this topic, we hope to address a number of very significant issues in this field that are not classically discussed in the technical literature.
