P3333.1.2 - Standard for the Perceptual Quality Assessment of Three Dimensional (3D) Contents based on Physiological Mechanisms

The purpose of this standard is to define quality metrics for the quality assessment, and establish guidelines for reducing risks to users entertaining 3D contents over 3D displays, and 3D devices. The major parameters dealt with in this standard include viewers' characteristics, visual contents, visual environment, display and devices described in the scope. Although metrics and methods for assessing quality of images and videos on 2 dimensional (2D) displays have been established, there has been little progress in doing so in the field of the 3D domain. This is, in part, due to the fact that 3D quality metrics need to take into account additional factors accrued from the dimension extension. Since the visual quality is eventually determined by the human eye, this standard will define how each human factor makes an effect on the visual quality over the 3D domain. This standard provides objective 3D image and video quality metrics that are in agreement with subjective human judgments and previous researched in the academy and the industry.This standard establishes methods of quality assessment of 3D 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 image and video contents: compression distortion, such as multi-view image and video compression, interpolation distortion by intermediate view rendering, such as 3D warping, view synthesis, structural distortion, such as bit errors on wireless/wired transmission errors, visual attention according to the quality degradation. Key items needed to characterize the 3D database in terms of the human visual system. These key factors are constructed in conjunction with the visual factors used to perceptual quality and visual attention.
