On the bandwidth of the plenoptic function
http://www.ifp.illinois.edu/%7Eminhdo/publications/plenoptic.pdf WebFig 6: Plenoptic Spectrum The Essential Bandwidth The plenoptic spectrum of the slanted plane is band-unlimited in both ωv and ωt, hence we cannot define an exact bandwidth region. However, we can define the Essential Bandwidth[5]: A finite region that contains 90% of the signal’s energy. Central Concept: The plenoptic function is

WebThe plenoptic function describes the information available to an observer at any point in space and time. Shown here are two schematic eyes-which one should consider to have punctate pupils-gathering pencils of light rays. A real observer cannot see the light rays coming from behind, but the plenoptic function does include these rays.
