The effect of crosstalk on depth magnitude in thin structures

Stereoscopic displays must present separate images to the viewer's left and right eyes. Crosstalk is the unwanted contamination of one eye's image from the image of the other eye. It has been shown to cause distortions, reduce image quality and visual comfort and increase perceived workload when performing visual tasks. Crosstalk also affects one's ability to perceive stereoscopic depth although little consideration has been given to the perception of depth magnitude in the presence of crosstalk. In this paper we extend a previous study (Tsirlin, Allison & Wilcox, 2010, submitted) on the perception of depth magnitude in stereoscopic occluding and non-occluding surfaces to the special case of crosstalk in thin structures. Crosstalk in thin structures differs qualitatively from that in larger objects due to the separation of the ghost and real images and thus theoretically could have distinct perceptual consequences. To address this question we used a psychophysical paradigm, where observers estimated the perceived depth difference between two thin vertical bars using a measurement scale. Our data show that crosstalk degrades perceived depth. As crosstalk levels increased the magnitude of perceived depth decreased, especially for stimuli with larger relative disparities. In contrast to the effect of crosstalk on depth magnitude in larger objects, in thin structures, a significant detrimental effect was found at all disparities. Our findings, when considered with the other perceptual consequences of crosstalk, suggest that its presence in S3D media even in modest amounts will reduce observers' satisfaction.

“…Pala et al [12] found that perceived workload increased in the presence of crosstalk in a task where observers were asked to align rods in depth. Still other studies have reported reduced visual comfort with increasing crosstalk [2], [13], [14]. Furthermore, crosstalk over 5% was found to cause a reduction in viewing comfort, especially for images containing large disparities [2].…”

Abstract-Crosstalk in stereoscopic displays is defined as the leakage of one eye's image into the image of the other eye. All popular commercial stereoscopic systems suffer from crosstalk to some extent. Studies show that crosstalk causes distortions, reduces image quality and visual comfort, and increases perceived workload. Moreover, there is evidence that crosstalk effects depth perception from disparity. In the present paper we present two experiments. The first addresses the effect of crosstalk on the perceived magnitude of depth from disparity. The second examines the effect of crosstalk on the magnitude of depth perceived from monocular occlusions. Our data show that crosstalk has a detrimental effect on depth perceived from both cues, but it has a stronger effect on depth from monocular occlusions. Our findings taken together with previous results suggest that crosstalk, even in modest amounts, noticeably degrades the quality of stereoscopic images.

“…Therefore, it is possible that the evaluation of fatigue using only one indicator leads to low reliability. The evaluation of fatigue using multiple indicators is desirable and may increase the reliability of evaluation [16]. However, researches about the integration of multiple objective indicators, their variations along time and sensitivities to reflect subjective visual fatigue are rare.…”

Stereoscopic displays are promising and have many applications in various fields because they can provide amazing visual effects. However, one of the inevitable problems is that they also cause visual fatigue after durative viewing. Recent years, many researches have been proposed on the visual fatigue during stereoscopic viewing. But there are very few researches on the visual fatigue during a continuous viewing process, especially for those combine both subjective and objective evaluation. Besides, with the development and popularization of mobile devices, it is now possible for users to experience stereoscopic effects using mobile devices anytime and anywhere. In this paper, a comprehensive evaluation method is proposed. Subjective scores, Electrocardiograph (ECG) and eye movement of all subjects were collected when they were viewing stereoscopic videos. These data were then used to analyze the change of the visual fatigue during viewing. A mobile device was adopted and a comparative experiment was designed to assess the change of the visual fatigue when viewing 2D and 3D content respectively. Eighteen subjects were employed in the experiment, and the results show that the visual fatigue is generally greater when viewing 3D contents than when viewing similar 2D contents.
