Richardson-Lucy Deblurring for Moving Light Field Cameras [article]

Donald G. Dansereau, Anders Eriksson, Jürgen Leitner
2017 arXiv   pre-print
We generalize Richardson-Lucy (RL) deblurring to 4-D light fields by replacing the convolution steps with light field rendering of motion blur.  ...  The method deals correctly with blur caused by 6-degree-of-freedom camera motion in complex 3-D scenes, without performing depth estimation.  ...  Blind deblurring, in which the motion of the camera and the deblurred image are jointly estimated, is left as future work.  ...
