JPEG compression of the left and right components of a stereo image pair is a way to save valuable bandwidth when transmitting stereoscopic images. This paper presents results on the effects of camera-base distance and JPEG-coding on overall image quality, perceived depth, perceived sharpness and perceived eye-strain. In the experiment, two stereoscopic still scenes were used, varying in depth (three different camera-base distances: 0, 8 and 12 cm) and compression ratio (4 levels: original, 1… Expand
Evaluation of Asymmetric Stereo Video Coding and Rate Scaling for Adaptive 3D Video Streaming
TLDR
It is shown that below this just-noticeable asymmetry threshold, where subtle artifacts start to appear, symmetric coding performs better than asymmetric coding in terms of perceived 3D video quality, and that the choice between asymmetric vs. symmetrical coding depends on PSNR; hence, the available total bitrate.

Effect of camera separation on the viewing experience of stereoscopic photographs
TLDR
The results showed that participants were able to perceive the change of depth range even though the images were shown in random order without a reference depth scale, and the highest naturalness of depth sensation and viewing experience were achieved with 2 cm to 6 cm camera separation in every content.

TLDR
A no-reference quality metric for stereoscopic images is proposed based on a top-down method modeling the binocular quality perception of the human visual system in the context of blurriness and blockiness. Expand
Geometric and subjective analysis of stereoscopic I3A cluster images
TLDR
This paper presents a geometric and subjective analysis of stereoscopic versions of close range I3A clusters (Subject- Camera distances below 5 m) and indicates that scenes with narrow depth should not be imaged with a long camera separation just to fill the depth budget of the display. Expand
Using distortion and asymmetry determination for blind stereoscopic image quality assessment strategy
TLDR
A blind/NR quality assessment strategy based on the identification of the distortion type in order to select the most efficient impairment measure in addition to the determination of whether a stereo-pair is symmetrically or asymmetrically distorted to account for the binocular fusion properties is proposed.

Capturing the added value of three-dimensional television : viewing experience and naturalness of stereoscopic images
The term "image quality" is often used to describe the performance of an imaging system. Recent research showed however that image quality may not be the most appropriate term to capture theExpand
Stereo Image Quality Assessment Using Visual Attention and Distortion Predictors
TLDR
A visual attention and depth assisted stereo image quality assessment model (VAD-SIQAM) is devised that consists of three main components, i.e., stereo attention predictor, depth variation (DV), and stereo distortion predictor (SDP). Expand
Coding of full-parallax multiview images
TLDR
This novel approach is able to concentrate the energy of a multi-view image much better than any two-dimensional or three-dimensional transform suggested so far, and much higher compression ratios can be reached. Expand
Perception of detail in 3D images
TLDR
The results show that the 3D image needed to be blurred more than the 2D image, which confirms the earlier qualitative findings that 3D images contain perceptually more details than 2D images with the same spatial resolution. Expand

Stereoscopic image coding: Effect of disparate image-quality in left- and right-eye views
TLDR
The results showed that the subjective quality of a stereo image sequence fell approximately midway between the quality of the left- and right-eye views, consistent with known properties of binocular vision, in particular with the averaging of brightness and contrast of stimuli presented to the two eyes. Expand
Psychovisual aspects of viewing stereoscopic video sequences
In comparison to conventional displays, 3D stereoscopic displays convey additional information about the 3D structure of a scene by providing information that can be used to extract depth. In theExpand
Data compression of stereopairs
TLDR
It is proved that the rate distortion limit for coding stereopairs cannot in general be achieved by a coder that first codes and decodes the right picture sequence independently of the left picture sequence, and then codes anddecodes theleft picture sequence given the decoded right picture sequences. Expand
Stereo image quality: effects of spatio-temporal resolution
TLDR
It was found that spatial filtering of one channel of a stereo video-stereo may be an effective means of reducing transmission bandwidth, and the overall sensation of depth was unaffected by low-pass filtering. Expand
Stereo image quality: effects of mixed spatio-temporal resolution
TLDR
It was found that spatial filtering of one channel of a stereo video-sequence may be an effective means of reducing the transmission bandwidth: the overall sensation of depth was unaffected by low-pass filtering, while ratings of quality and of sharpness were strongly weighted towards the eye with the greater spatial resolution. Expand
Effects of stereoscopic filming parameters and display duration on the subjective assessment of eye strain
TLDR
The results showed that subjective stereoscopic image quality can be described as a function of reported eye strain and perceived depth, most pronounced for the stereoscopic images that were produce using a short convergence distance. Expand
Predicted and perceived quality of bit-reduced gray-scale still images
TLDR
It will be demonstrated in this chapter how a small image set of scenes can be selected for the purpose of discriminating between the predictions of instrumental quality measures, and the usefulness of quality measures can be ascertained from a small, well chosen set of images. Expand
Unequal weighting of monocular inputs in binocular combination: implications for the compression of stereoscopic imagery.
TLDR
It is concluded that blur, but not blockiness, is an acceptable form of monocular degradation, provided that binocular vision assigns greater weight to the nondegraded input. Expand
Visual comfort of binocular and 3D displays
Imperfections in binocular image pairs can cause serious viewing discomfort. For example, in stereo vision systems eye strain is caused by unintentional mismatches between the left and right eyeExpand
Evaluation of stereoscopic picture quality with CFF.
TLDR
CFF is an effective measure for objectively measuring the fatigue of television observers, including observers of binocular stereoscopic television, and is found that with respect to CFF viewing of around 30 min was allowable. Expand
