Just Noticeable Depth Difference of Human during Viewing of Dynamic Random Dot Stereograms

Just Noticeable Depth Difference (JNDD) describes the sensitivity of human for depth difference to Stereoscopic three Dimensional (S3D) viewing, which is an important cue in research on Human Visual System (HVS). Understanding the factors of human depth perception is helpful to the research on stereo image processing and optimization, which is heavily based on exploitation of HVS. The traditional JNDD measurement test cannot avoid the impact of monocular stimulation and psychological depth cue. In this paper, a new JNDD measurement method for only binocular stimulation and pure physiological depth cue based on dynamic Random Dot Stereogram (RDS) technique is proposed. Then subjective test are performed on a S3D display with two JNDD measurement methods: the proposed one and a traditional one for binocular disparity depth cue. The results show that observers are more sensitive to the depth difference in the proposed methods.
