This standard establishes methods for quality assessment of 3D, UHD and HDR 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, UHD and HDR image and video contents: — Compression distortion, such as multi-view image and video compression, — Interpolation distortion by intermediate view rendering, such as 3D, UHD and HDR warping, view synthesis, — Structural distortion, such as bit errors on wireless/wired transmission errors, — Visual attention according to the quality degradation. — Deep learning based model for saliency detection and QoE assessment. Key items are needed to characterize the 3D, UHD and HDR 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.
The purpose of this standard is to define quality metrics for 3D, UHD and HDR quality assessment, and establish guidelines in order for users to entertain contents 3D/UHD/HDR displays and devices without any risks. The major parameters considered in this standard include viewers’ characteristics, visual contents, visual environment and 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/UHD/HDR domain. This is, in part, due to the fact that these quality metrics need to take into account additional factors accrued from the dimension extension and resolution changes. Since the visual quality is eventually determined by the human eye, this standard will define how each human factor affects the visual quality of 3D, UHD, and HDR contents. This standard provides objective 3D/UHD/HDR image and video quality metrics that are in agreement with subjective human judgments and previously researched in the academy and the industry
Revision Standard – Active – Draft. The world is witnessing a rapid advance in Stereoscopic 3D, and Ultra high definition (UHD) technology. As a result, the need for accurate quality and visual comfort assessment techniques to foster the display device industry as well as signal processing area. In this standard, thorough assessments with respect to the human visual system (HVS) for S3D and UHD contents shall be presented. Moreover, several image and video databases are also publicly provided for any research purpose.
