This paper analyzes the technical characteristic of three-dimensional display technology (3DTV) system and some core technologies yet to be solved.It points out the ways to solve these problems and presents an effective solution for the discomfort of watching the three-dimensional TV.
Depth maps are used for synthesis virtual view in free-viewpoint television (FTV) systems.When depth maps are derived using existing depth estimation methods,the depth distortions will cause undesirable artifacts in the synthesized views.To solve this problem,a 3D video quality model base depth maps (D-3DV) for virtual view synthesis and depth map coding in the FTV applications is proposed.First,the relationships between distortions in coded depth map and rendered view are derived.Then,a precisely 3DV quality model based depth characteristics is develop for the synthesized virtual views.Finally,based on D-3DV model,a multilateral filtering is applied as a pre-processed filter to reduce rendering artifacts.The experimental results evaluated by objective and subjective methods indicate that the proposed D-3DV model can reduce bit-rate of depth coding and achieve better rendering quality.
