Perceptual attributes of crosstalk in 3D images
Nowadays, crosstalk is probably one of the most annoying distortions in 3D displays. So far, display designers still have a relative lack of knowledge about the relevant subjective attributes of crosstalk and how they are combined in an overall 3D viewing experience model. The aim of the current experiment is to investigate three perceptually important attributes influencing the overall viewing experience: perceived image distortion, perceived depth, and visual strain. The stimulus material used in this experiment consisted of two natural scenes varying in depth (0, 4, and 12cm camera base distance) and crosstalk level (0, 5, 10, and 15%). Subjects rated the attributes according to the ITU BT.50010 in a controlled experiment. Results show that image distortion ratings show a clear increase with increasing crosstalk and increasing camera base distance. Especially higher crosstalk levels are more visible at larger camera base distances. Ratings of visual strain and perceived depth only increase with increasing camera base distance and remain constant with increasing crosstalk (at least until 15% crosstalk).
