Paper Abstract

From a signal processing perspective, we examine the main factors defining the visual quality of autostereoscopic 3-D displays, which are beginning to reproduce the plenoptic function with increasing accuracy. We propose using intuitive visual tools and ray-tracing simulations to gain insight into the signal processing aspects, and we demonstrate the advantages of analyzing what we call mixed spatial-angular spaces. With this approach we are able to intuitively demonstrate some basic limitations of displays using anisotropic diffusers or lens arrays. Furthermore, we propose new schemes for improved performance.
