Abstract:The paper aims at removing the aliasing effects for the whole focal stack generated from a sparse 3D light field, while keeping the consistency across all the focal layers. We first explore the structural characteristics embedded in the focal stack slice and its corresponding frequency-domain representation, i.e., the focal stack spectrum (FSS). We also observe that the energy distribution of FSS always locates within the same triangular area under different angular sampling rates, additionally the continuity … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
