Abstract
The spectrum analysis discussed in the previous chapter lays the foundation of light field sampling. The next step is to sample the light field according to the spectrum and make sure there is no aliasing during this process, so that we can reconstruct the continuous light field with no artifacts. Early works on light field sampling mostly considered rectangular sampling [30, 8]. As a well-known fact in multidimensional signal processing theory [11], rectangular sampling is not the best sampling strategy in high-dimensional space, where the light field stands. In this chapter, we study the sampling process of the light field with the generalized sampling theory and treat rectangular sampling as a special case, which turns out to be the best choice for real-world scenes in terms of the tradeoff between complexity and accuracy.
