Restoration of distorted images is one of the most interesting and important problems of image processing - from the theoretical, as well as from the practical point of view. There are especial cases: blurring due to incorrect focus and blurring due to movement - and these very defects which each of you knows very well, and which are very difficult to repair were selected as the subject of this article. As for other image defects noise, incorrect exposure, distortion , the humanity has learned how to correct them, any good photo editor has that tools. Why is there almost no means for correction of blurring and defocusing except unsharp mask - maybe it is impossible to do this at all? In fact, it is possible - development of a respective mathematical theory started approximately 70 years ago, but like other algorithms of image processing, deblurring algorithms became wide-used just recently. So, below is a couple of pictures to demonstrate the WOW-effect:.
