The role of monocularly visible regions in depth and surface perception [PDF]

, 2009
The mainstream of binocular vision research has long been focused on understanding how binocular disparity is used for depth perception. In recent years, researchers have begun to explore how monocular regions in binocularly viewed scenes contribute to ...

A Depth-Enhanced Holographic Super Multi-View Display Based on Depth Segmentation

Micromachines, 2023
A super multi-view (SMV) near-eye display (NED) effectively provides depth cues for three-dimensional (3D) display by projecting multiple viewpoint or parallax images onto the retina simultaneously.

High resolution digital holographic synthetic aperture applied to deformation measurement and extended depth of field method [PDF]

, 2010
This paper discusses the potential of the synthetic-aperture method in digital holography to increase the resolution, to perform high accuracy deformation measurement, and to obtain a three-dimensional topology map.

“Depth of field” or “negative forms”: space/syntax from HDR digital photography to hypermedia navigation

Sillages Critiques, 2016
The article explores the notions related to the perception of the figure/ground contrast in the visual arts. Starting from the history of the words “negative” and “depth of field” in 19th-century photography, it studies solutions such as the possible ...

Using Gaze-Contingent Depth of Field to Facilitate Depth Perception [PDF]

i-Perception, 2014
The lens system of the human eye has a limited depth of field that creates blur patterns that depend on its focus and the relative distances of the observed objects.

Use of Miniature Step Gauges to Assess the Performance of 3D Optical Scanners and to Evaluate the Accuracy of a Novel Additive Manufacture Process

Sensors, 2020
In this work, we show how miniature step gauges featuring unidirectional and bidirectional lengths can be used to assess the performance of 3D optical scanners as well as the accuracy of novel Additive Manufacturing (AM) processes. A miniature step gauge

Integral Imaging Display System Based on Human Visual Distance Perception Model

Sensors, 2023
In an integral imaging (II) display system, the self-adjustment ability of the human eye can result in blurry observations when viewing 3D targets outside the focal plane within a specific range.

Large Depth of Range Maxwellian-Viewing SMV Near-Eye Display Based on a Pancharatnam-Berry Optical Element

IEEE Photonics Journal, 2022
In order to overcome the accommodation and convergence (A-C) conflict that commonly causes visual fatigue in AR display, we propose a Maxwellian-viewing-super-multi-view (MV-SMV) near-eye display system based on a Pancharatnam-Berry optical element (PBOE)

Depth-Enhanced Holographic Super Multi-View Maxwellian Display Based on Variable Filter Aperture

Micromachines, 2023
The super multi-view (SMV) near-eye display (NED) effectively provides depth cues for three-dimensional (3D) displays by projecting multiple viewpoint images or parallax images onto the retina simultaneously. Previous SMV NED suffers from a limited depth

Perception of relative depth interval : Systematic biases in perceived depth [PDF]

, 2012
Given an estimate of the binocular disparity between a pair of points and an estimate of the viewing distance, or knowledge of eye position, it should be possible to obtain an estimate of their depth separation.
