Fast approximate 4D:3D discrete Radon transform, from light field to focal stack with O(N⁴) sums

SPIE Proceedings, 2011
In this work we develop a new algorithm, that extends the bidimensional Fast Digital Radon transform from Gotz and Druckmuller (1996), to digitally simulate the refocusing of a 4D light field into a 3D volume of photographic planes, as previously done by Ren Ng et al. (2005), but with the minimum number of operations.
