Transforming Monochromatic Images into 3D Holographic Stereograms Through Depth-Map Extraction

Applied Sciences
Traditional holographic printing techniques prove inadequate when only input data are available. Therefore, this paper proposes a new artificial-intelligence-based process for generating digital holographic stereograms from a single black-and-white ...

Resolution priority holographic stereogram based on integral imaging with enhanced depth range.

Optics Express, 2019
Conventional holographic stereogram (HS) can be generated through fast Fourier transforming parallax images into hogels. Conventional HS uses multiple plane waves to reconstruct 3D images with low resolution and is similar to the principle of depth ...

High-quality holographic stereogram generation using four RGBD images.

Applied Optics, 2020
To computer-generate high-quality holographic stereograms, a huge number of images must be provided: several hundred for a horizontal parallax and the square of this number for a full parallax.

Analysis on the reconstruction error of EPISM based full-parallax holographic stereogram and its improvement with multiple reference plane.

Optics Express, 2019
To reduce the reconstruction error of holographic stereogram fabricated by effective perspective images' segmentation and mosaicking method (EPISM), a multiple-reference-plane (MRP) approach is proposed and validated.

Speckle regularization and miniaturization of computer-generated holographic stereograms

Optics Express, 2016
Holographic stereograms produce multiple parallax images that are seen from multiple viewpoints. Because random phase distributions are added to the parallax images to remove areas where images cannot be seen in the viewing area, speckles are generated in the reconstructed images.

Method of single-step full parallax synthetic holographic stereogram printing based on effective perspective images' segmentation and mosaicking.

Optics Express, 2017
With the principle of ray-tracing and the reversibility of light propagation, a new method of single-step full parallax synthetic holographic stereogram printing based on effective perspective images' segmentation and mosaicking (EPISM) is proposed.
