WebThe light field is a vector function that describes the amount of light flowing in every direction through every point in space. The space of all possible light rays is given by the five-dimensional plenoptic function, and the magnitude of each ray is given by its radiance. Michael Faraday was the first to propose that light should be interpreted as a field, much … http://chenlab.ece.cornell.edu/Publication/Cha/icassp03_Cha2.pdf

Throughout the last decade, an ever increasing number of approaches to acquiring individual plenoptic di-mensions have been proposed [4]. We discuss the acquisi-
Webplenoptic function for IBR sampling analysis. We call the new representation surface plenoptic function (SPF). There exists a unique mapping between the SPF and the IBR representation. We show that when this mapping is well defined, we are able to do the spectral analysis for generic scenes including occluded or non-Lambertian ones.
