Abstract

We propose an approach to produce computer generated holograms (CGHs) from image pairs of a real-world scene. The ratio of the three-dimensional (3D) physical size of the object is computed from the image pair to provide the correct depth cue. A multilayer wavefront recording plane method completed with a two-stage occlusion culling process is carried out for wave propagation. Multiple holograms can be generated by propagating the wave toward the desired angles, to cover the circular views that are wider than the viewing angle restricted by the wavelength and pitch size of a single hologram. The impact of the imperfect depth information extracted from the image pair on CGH is examined. The approach is evaluated extensively on image pairs of real-world 3D scenes, and the results demonstrate that the circular-view CGH can be produced from a pair of stereo images using the proposed approach.
