Software restores blurred images

Software restores blurred images

A Russian software engineer has developed a downloadable software tool that can be used to restore defocused and blurred images.

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.

For his part, Vladimir Yuzhikov -- who is currently working as an application developer at Deutsche Bank -- wanted to deal with the problem by developing code that corrects for blurring due to incorrect focus and movement.

Written in C++ using Qt 4.8 -- a development framework from Digia (Helsinki, Finland) with tools designed to streamline the creation of applications and user interfaces for desktop, embedded and mobile platforms – Yuzhikov’s SmartDeblur tool can correct for out of focus blur, motion blur and Gaussian blur.

Yuzhikov says that the software takes around 300msec to process an image of 2048 x 1500 pixels. But processing of larger images may take a few minutes.


To explain the principles behind the software, Yuzhikov has written an extensive technical article that can be found here. The article is also available in the Russian language here.

The latest source and binaries are available on GitHub here. All source files are under the GPL v3 license.
