On the bandwidth of the plenoptic function
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 Webspectrum of the plenoptic function under FSW and FFV in Section IV and derive its exact expression for a slanted plane. In Section V, we determine the essential bandwidth for …

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.

WebThe plenoptic function enables Image-based rendering (IBR) to be viewed in terms of sampling and reconstruction. Thus the spatial sampling rate can be determined through spectral analysis of the plenoptic function. In this paper we examine the bandwidth of the plenoptic function when both the field of view and the scene width are finite.
