Fourier Slice Photography
Fourier Slice Photography Ren NgStanford University In ACM Transactions on Graphics, July 2005 (Proceedings of SIGGRAPH) Abstract This paper contributes to the theory of photograph formation from light fields. The main result is a theorem that, in the Fourier domain, a photograph formed by a full lens aperture is a 2D slice in the 4D light field. Photographs focused at different depths correspond
