Multi-view plus depth (MVD), as a video representation supporting view synthesis based on depth video, has attracted more and more attention for the free view video (FVV) application. It is a challenge to efficiently compress the multi-view depth data in MVD format. In this paper, we explore the geometric relationships in 3D space and propose a geometric mapping assisted (GMA) multi-view depth video...
Summary form only given. In 3D video (3DV), the virtual view images are commonly synthesized by the color and depth images of the reference views with image based rendering (IBR). Thus, in 3DV coding, to provide the high-quality interactive viewpoint video to audience, it is necessary to jointly optimize coding efficiency of color and depth images at a given bit-rate by rate-distortion (R-D) property...
In this paper, an efficient method to synthesize 3D video in real-time from binocular stereo camera is presented. Our stereo camera consists of two pre-calibrated cameras with the optical axis perpendicular to the camera displacement. While much work has been done on stereo processing recently, most of them are focused on high-quality depth map generation, which are usually time-consuming and unsuitable...
The ability to interactively and seamlessly roam in the scenario while watching a video through IP network is an exciting visual experience. In this work, we implemented a 3D TV system with real-time data acquisition, compression, Internet transmission, light field rendering, and free-viewpoint control of dynamic scenes. Our system consists of an 8times8 light field camera array, 16 producer PCs,...
Compression and calculation efficiency are two key problems for light field coding. While nearly all works focus on one quality and neglect the other, this paper introduces a novel color block truncation algorithm using hierarchical bit-plane prediction (CBTC-HBPP) to chase for them both. This approach first performs two-color-truncation in block classes extracted from the whole light field. The yielding...
