Abstract/OtherAbstract:
Unrestricted positioning of elements in random-dot stereograms with steep disparity gradients, such as stereo-transparent stereograms depicting overlaid surfaces, can produce perceptual artifacts similar to disparity noise. It is shown that these artifacts hinder the segregation of overlaid surfaces in transparent random-dot stereograms and thus disrupt the perception of stereotransparency. This effect is intensified with increases in the overall element density of the stimuli. We outline the origin of this phenomenon and discuss techniques to prevent such artifacts.
