A geometric model of an autostereoscopic 3D display is described herein. This model is based on the geometry of typical display devices and on the projective transformations that provide periodicity in the projective space. The formulas for the transformations between regions and spaces are provided. The model can be applied to the study of an operation of the multiview, integral, plenoptic, and lightfield displays. A practical application considered in this paper is the multiview wavelet transform. ARTICLE HISTORY

“…The loss value between the OII and the calculated display image (CI) is calculated using Eq. ( 8) as LossOII,CI = α × MSEOII,CI β × SSIMOII,CI, (8) where α β = 1 and 0 < α < 1, 0 < β < 1. In this experiment, the lowest loss values were obtained for α = 0.6 and β = 0.4.…”

“…Three-dimensional (3D) display technology is capable of providing real and natural 3D perception, and, consequently, various efforts have been made to advance this technology further [1][2][3][4][5] . Light field display, which is considered as the most promising 3D display technology, can reconstruct the real light field distribution of a real 3D scene [6][7][8][9] . Integral imaging (II), a 3D display method that can realize full parallax and true color, and provide depth information, was first proposed, to the best of our knowledge, by Lippmann in 1908 [10] .…”

In the integral imaging light field display, the introduction of a diffractive optical element (DOE) can solve the problem of limited depth of field of the traditional lens. However, the strong aberration of the DOE significantly reduces the final display quality. Thus, herein, an end-to-end joint optimization method for optimizing DOE and aberration correction is proposed. The DOE model is established using thickness as the variable, and a deep learning network is built to preprocess the composite image loaded on the display panel. The simulation results show that the peak signal to noise ratio value of the optimized image increases by 8 dB, which confirms that the end-to-end joint optimization method can effectively reduce the aberration problem.

Light field 3D displays represent a major step forward in visual realism, providing glasses-free spatial vision of real or virtual scenes. Applications that capture and process live imagery have to process data captured by potentially tens to hundreds of cameras and control tens to hundreds of projection engines making up the human perceivable 3D light field using a distributed processing system. The associated massive data processing is difficult to scale beyond a specific number and resolution of images, limited by the capabilities of the individual computing nodes. We therefore analyze the bottlenecks and data flow of the light field conversion process and identify possibilities to introduce better scalability. Based on this analysis we propose two different architectures for distributed light field processing. To avoid using uncompressed video data all along the processing chain, we also analyze how the operation of the proposed architectures can be supported by existing image / video codecs.
