Feedforward data-aided phase noise estimation from a DCT basis expansion [PDF]
, 2008 This contribution deals with phase noise estimation from pilot symbols. The phase noise process is approximated by an expansion of discrete cosine transform (DCT) basis functions containing only a few terms.

International Journal of Psychological Research, 2020 Non-immersive VR environments are related to the least interactive application of VR techniques, such that interaction with the VR environment can occur commonly by 3D-TV without full immersion into the environment. This study presents how 3D-TV exposure

Low‐Complexity Texture Video Coding Based on Motion Homogeneity for 3D‐HEVC
Scientific Programming, Volume 2019, Issue 1, 2019., 2019 Three‐dimensional extension of the high efficiency video coding (3D‐HEVC) is an emerging international video compression standard for multiview video system applications. Similar to HEVC, a computationally expensive mode decision is performed using all depth levels and prediction modes to select the least rate‐distortion (RD) cost for each coding unit (

Study of depth bias of observers in free viewing of still stereoscopic synthetic stimuli
Journal of Eye Movement Research, 2012 Observers’ fixations exhibit a marked bias towards certain areas on the screen when viewing scenes on computer monitors. For instance, there exists a well-known “center-bias” which means that fixations are biased towards the center of the screen during ...
