“…Instead, crossed disparity makes the target close the observer, and the observer can thus be made more sensitive to the color identification, leading to fusion limit decreases. Usually, we think that color vision is a lowlevel monocular vision, while stereo vision is a highlevel binocular vision, so the influence of color information on binocular disparity fusion is positive [21], [22], [30]. But we have shown here that the binocular disparity fusion would also affect the color fusion.…”

“…However, it is possible for stereopsis and color rivalry to coexist when a common stimulus is shown to both eyes with disparity and those two monocular stimuli differ only in color but share an iso-luminance polarity. In other words, iso-luminance information allows for fusion and stereopsis [21], [22], while the discrepant color component allows for the rivalry. The visual discomfort has always been described as the number one health issue for the application and development of 3D industry [23], [24].…”

When the color asymmetry between the left and right eyes exceeds a threshold value, named binocular color fusion limit, the color rivalry is said to occur. For stereoscopic displays, the horizontal disparity is the most important information to produce depth perception. When the stereo pair stimuli are presented separately to both eyes with disparities and those two stimuli also differ in color but share an iso-luminance polarity, it is possible for stereopsis and color rivalry to coexist. In this paper, we conducted a psychophysical experiment to quantitatively measure the color fusion limit at different disparity levels. In particular, it examined how disparities affect the binocular color fusion limit. A binocular color fusion limit was measured at five relative disparity levels: 0, ±60, and ±120 arc minutes for five sample color points, which were selected from the 1976 CIE u'v' chromaticity diagram. The experimental results show that the color fusion limit for each sample point varies with the disparity magnitude, disparity sign, and color direction. It is new research finding that the color fusion limit increases as the disparity increases from −120 to +120 arc minutes. The average color fusion limit ranges from 0.036 to 0.064 in terms of Euclidean distance in the u'v' chromaticity diagram ( E u v ). The new finding shows that the human eye has different information processing mechanisms for crossed disparity (sign −) and uncrossed disparity (sign +), and uncrossed disparity can contribute to color fusion. We suggest that the color fusion limit varies with the color direction, but it has nothing to do with the distribution of cone cells. The color fusion limit was quantified by using ellipses in the chromaticity diagram, and the axis of the ellipses ranges from 0.017 to 0.145 E u v . The experiments and data analysis in this paper indicate that the binocular disparity fusion affects binocular color fusion. This research result can strongly support 3D system design and 3D content creation.

“…Besides, Gregory and De Weert also indicated that stereopsis was not possible with isoluminant random‐dot‐stereograms too. Nevertheless, stereopsis from chromatic isoluminant random‐dot stereogram was reported in later research by De Weert and Sadza, Jiménez et al ., Isono and Yasuda, and Chen et al ., etc. Although lots of different experiment control parameters were used in these studies, for example, different horizontal disparity ranges and the control of chromatic aberration, the positive results for the color contribution to stereopsis are similar.…”

Abstract:The relationship between reaction time and perceived contrast of random-dot-stereograms has been investigated in this article. First, reaction times of random-dot stereograms with luminance contrast variations and chromatic contrast variations at isoluminance were examined. Further experiments of reaction times were measured for random-dot stereograms filtered by a two-dimensional Gaussian filter. The results clearly indicate that reaction time gradually decreases as contrast increases and level outs when contrast approaches to some value. Furthermore, reaction times for same contrast were shorter for luminance changes than the chromatic variations along the red-green axis, which in turn were shorter than those along blue-yellow axis. Therefore, it could be concluded that luminance contrast cues are more effective than chromatic contrast cues at isoluminance in facilitating stereo perception. On the other hand, it has been found that there was no apparent difference of reaction times for filtered random-dot stereograms, compared with the unfiltered cases. Finally, there are large inter-subject variations in stereo perception.

“…It is well known that certain aspects of the design of static stereoscopic stimuli are important for correct and easy perception, such as the eccentricity of the stimulus, the contrast and the color of the signal, the luminance, or the relationship between reference and target (Chen, Shi, Tai, & Yun, 2012;Zhang et al, 2016). Perception of MID relies on different cues from those for the perception of static 3D scenes (for the impact of dynamic changes, see Brenner, Van Den Berg, & Van Damme, 1996;Tidbury, Brooks, O'Connor, & Wuerger, 2016;Watanabe et al, 2008).…”

Enhancing Motion-In-Depth Perception of Random-Dot Stereograms

Random-dot stereograms have been widely used to explore the neural mechanisms underlying binocular vision. Although they are a powerful tool to stimulate motion-in-depth (MID) perception, published results report some difficulties in the capacity to perceive MID generated by random-dot stereograms. The purpose of this study was to investigate whether the performance of MID perception could be improved using an appropriate stimulus design. Sixteen inexperienced observers participated in the experiment. A training session was carried out to improve the accuracy of MID detection before the experiment. Four aspects of stimulus design were investigated: presence of a static reference, background texture, relative disparity, and stimulus contrast. Participants' performance in MID direction discrimination was recorded and compared to evaluate whether varying these factors helped MID perception. Results showed that only the presence of background texture had a significant effect on MID direction perception. This study provides suggestions for the design of 3D stimuli in order to facilitate MID perception.
