scope:

This standard establishes methods for quality assessment of 3D and UHD contents based on physiological mechanisms such as perceptual quality and visual attention. This standard identifies and quantifies the following causes and visual attention of perceptual quality degradation for 3D and UHD image and video contents:

- Compression distortion, such as multi-view image and video compression

- Interpolation distortion by intermediate-view rendering, such as 3D and UHD warping, view synthesis

- Structural distortion, such as bit errors on wireless/wired transmission errors

- Visual attention according to the quality degradation

Key items are needed to characterize the 3D and UHD database in terms of the human visual system. These key factors are constructed in conjunction with the visual factors used to perceive quality and visual attention
