eye (monocular cues) such as shadows, perspective and motion parallax.
Other cues like stereopsis and convergence (binocular cues) require the
cooperative work of both eyes. Thus depth perception of 3D video is
affected by both monocular and binocular cues (extracted from the colour
texture video and depth map). Also it is noted that the depth quality is more
sensitive to quality variation of the colour texture video than the depth map.
6.4 Modelling the Perceptual Attributes of 3D Video
This section attempts to objectively evaluate the quality attributes of colour-
plus-depth-based 3D video described in Section 6.2. A third experiment
