FI http://library.utia.cas.cz/separaty/2013/ZOI/flusser-0394767.pdf GAP103/11/1552 GA ČR cav_un_auth*0273618 In this paper, we propose a new registration method designed particularly for registering differently blurred images. Such a task cannot be successfully resolved by traditional approaches. Our method is inspired by traditional phase correlation, which is now applied to certain blur-invariant descriptors instead of the original images. This method works for unknown blurs assuming the blurring PSF exhibits an N-fold rotational symmetry. It does not require any landmarks. We have experimentally proven its good performance, which is not dependent on the amount of blur. In this paper, we explicitly address only registration with respect to translation, but the method can be readily generalized to rotation and scaling. 2014 JD 3 4 A 4a 20231122135724.5 RVO:67985556 http://hdl.handle.net/11104/0223843 COMPUTERSCIENCEARTIFICIALINTELLIGENCE|ENGINEERINGELECTRICALELECTRONIC 3.925 0.351 7.VII 0.03498 1.536 15929 427 1.507 ScienceCitationIndex Q1 91.748 89.079 Q1* Q1 2013 Soubory v repozitáři: flusser-0394767.pdf 84893548773 SCOPUS 000324382700020 WOS cav_un_epca*0253235 IEEE Transactions on Image Processing 1057-7149 1941-0042 Roč. 22 č. 9 2013 3676 3689 Institute of Electrical and Electronics Engineers
