Stereo/multiview picture quality: Overview and recent advances

Stereoscopic 3D content brings with it a variety of complex technological and perceptual issues. For the percept of depth to be convincing, consistent, and comfortable, a large number of parameters throughout the imaging and processing pipeline need to be matched correctly. In practice, tradeoffs are inevitable, which may then affect the quality or comfort of the 3D viewing experience. This paper reviews stereo/multiview picture quality from an engineering perspective. With a focus on recent or emerging approaches and technologies used in 3D systems, it addresses in particular depth issues, multiview issues, display issues, viewer issues, as well as possible measurements and standards for 3D quality.
