Recently, this area of research is dominated by blind deblurring, where neither the sharp image nor the blur are known. The majority of works, however, target scenarios where the captured scene is static and the blur is caused by camera motion, i.e. the whole image is blurred. In this work we address a similar yet different scenario: an object moves in front of a static background. Such object is blurred due to motion while the background is sharp and partially occluded by the object. The problem of blind deblurring in such setting has not been properly addressed in literature. We formally define the problem, discuss its solvability, and explain why it cannot be viewed as a special case of classical blind de-blurring. We propose a solution to the presented problem for a particular class of motions and demonstrate results on real data. cav_un_auth*0366810 IEEE International Conference on Image Processing 2018 (ICIP 2018) /25./ 20181007 20181010 Atény GR JD 20000 20200 20206 2019 2 PO RVO:67985556 http://hdl.handle.net/11104/0289350 S 1* Proceedings Paper Computer Science Software Engineering|Imaging Science Photographic Technology 2018 85062894265 SCOPUS PUBMED 000455181502196 WOS pdf 1.5MB cav_un_epca*0496137 Proceedings of the 25th IEEE International Conference on Image Processing 2018 978-1-4799-7062-9 2860 2864 Piscataway IEEE 2018
