We propose an algorithm that converts a full-parallax hologram to a horizontal-parallax-only (HPO) hologram for 3D display. We first record a full-parallax hologram of an object. Subsequently, we filter the hologram with a Gaussian low-pass filter and a fringe-matched filter along the vertical direction. The final filtered output becomes an HPO hologram. To the best of our knowledge, this is the first algorithm proposed for converting full-parallax holographic information to HPO-holographic information.
