Abstract
This paper proposes a stereoscopic model for DFD display that explains the continuous depth modulation and protruding depth perception. The model is composed of four steps: preparation of DFD images, geometrical calculation of viewed images, human visual function for detecting intensity changes, and stereoscopic depth perception. In this paper, two types of displayed images for DFD display are prepared: the former pairs are for conventional DFD, where a fused image is located between the layered images; the latter pairs are for protruding DFD, where a fused image is located closer than the foreground image or further than the background image. Viewed images at both eye positions are simulated geometrically in computer vision optics model. In order to detect intensity changes, we have utilized Laplacian operation on a Gaussian blurred image. Stereoscopic depths are calculated by matching the zero crossing position on the Laplacian operated images. It is revealed that our stereoscopic model explains both conventional and protruding DFDs.
