Blurs are first estimated in a small number of image patches. We derive a novel parametric blur interpolation method and discuss conditions under which it can be used to exactly calculate blurs for every pixel position. Having this information, we restore the sharp image by a standard regularization technique. Performance of the proposed method is experimentally validated. cav_un_auth*0294729 International conference on image processing, ICIP 2013 Melbourne 15.09.2013-18.09.2013 AU 2014 JD 4 PR RVO:67985556 http://hdl.handle.net/11104/0225515 S 2013 cav_un_epca*0425945 Proceedings of the 2013 IEEE International Conference on Image Processing ICIP 2013 978-1-4799-2341-0 577 581 Piscataway IEEE 2013
