Joint foveation-depth just-noticeable-difference model for virtual reality environment

In this paper, we develop a joint foveation-depth just-noticeable-difference (FD-JND) model to quantify the perceptual redundancy of image in the VR display environment. The proposed FD-JND model is developed with considerations on the effects of both foveation and depth. More specifically, experiments for the VR environment on synthesized stimuli are conducted based on luminance masking and contrast masking and the FD-JND model is developed accordingly. Subjective quality discrimination experiments between the noise contaminated images and original ones validate favorableness of the proposed FD-JND model.
