Optimizing visual comfort for stereoscopic 3D display based on color-plus-depth signals

Abstract

Visual comfort is a long-facing problem in stereoscopic 3D (S3D) display. In this paper, targeting to produce S3D content based on color-plus-depth signals, a general framework for depth mapping to optimize visual comfort for S3D display is proposed. The main motivation of this work is to remap the depth range of color-plus-depth signals to a new depth range that is suitable to comfortable S3D display. Towards this end, we first remap the depth range globally based on the adjusted zero disparity plane, and then present a two-stage global and local depth optimization solution to solve the visual comfort problem. The remapped depth map is used to generate the S3D output. We demonstrate the power of our approach on perceptually uncomfortable and comfortable stereoscopic images.

Extraction and investigation of biosignal features for visual discomfort evaluation

“…The rendering of stereoscopic images may have different set-ups which have a direct influence on the comfort of visual perception and ability to focus on the object of interest in the image. If there would be possible to estimate the comfort level during individual stereoscopic perception, various virtual camera separation parameters may be adjusted (Shao et al 2016) to avoid visually uncomfortable scenes in the rendered video stream. Virtual camera separation, used during the rendering of stereoscopic views, depending on the scene, causes different image disparities followed by too much or too littleperceived depth on a target display.…”

Evaluation of EEG-based Complementary Features for Assessment of Visual Discomfort based on Stable Depth Perception Time

“…The rendering of stereoscopic images may have different set-ups which have the direct influence on the comfort of visual perception and ability to focus on the object of interest in the image. If there would be possible to estimate the comfort level in real-time during individual stereoscopic perception, various virtual camera separation parameters may be adjusted [3] to avoid visually uncomfortable scenes in the rendered video stream. Virtual camera separation, used during the rendering of stereoscopic views, depending on the scene, causes different image disparities followed by too much or too little-perceived depth on a target display.…”
