Cover Story: This paper proposes an effective and fast method to produce automatically holographic 3D images from low-cost stereo cameras without user intervention. The presented algorithm retrieves images from a stereo camera, evaluates correlations between left and right images (by using the DeepFlow algorithm), and produces intermediate lightfield views which output holographic displays for slanted lenticular monitors, such as the new Looking Glass Holoplay device. Some intermediate processing steps are necessary to get realistic 3D images: Holoplay per-device calibration, left–right correlation, intermediate views, quilt creation, and final “native” multiview image generation. In order to speed up these processes and to reduce run-time computation, some Lookup Tables are introduced as a first step towards achieving 2D to 3D conversion in real-time. View this paper

We propose a novel multiple query retrieval approach, named weight-learner, which relies on visual feature discrimination to estimate the distances between the query images and images in the database. For each query image, this discrimination consist...

Morphing a Stereogram into Hologram

Livio Tenze

J. Imaging2020, 6(1), 1;https://doi.org/10.3390/jimaging6010001

2 January 2020

We developed a method to transform stereoscopic two-dimensional (2D) images into holograms via unsupervised morphing deformations between left (L) and right (R) input images. By using robust DeepFlow and light-field rendering algorithms, we establish...
