Is spatial super-resolution feasible using overlapping projectors?

An interesting issue of contemplation amongst researchers working on multi-projector displays is whether spatial superresolution can be achieved by overlapping images from multiple projectors. This paper presents a thorough theoretical analysis to answer this question using signal processing and perturbation theory. Our analysis is supported by results from a simulated overlapping projector display. This analysis shows that achieving spatial super-resolution using overlapping projectors is practically infeasible.
