For advanced 3D Video (3DV) applications, efficient data representations are investigated, which only transmit a subset of the views that are required for 3D visualization. From this subset, all intermediate views are synthesized from sample-dense color and depth data. In this paper, the method for reliability-based view synthesis from compressed multi-view + depth data (MVD) is investigated and corresponding...
A system for video on multiscopic 3D displays is considered where the data representation consists of multiview video plus scene depth. At most, 3 multiview video signals are being transmitted and used together with the depth data to generate intermediate views at the receiver. The paper presents an approach to such an intermediate view interpolation that separates unreliable image regions along depth...
In this paper, a system for video rendering on multiscopic 3D displays is considered where the data is represented as layered depth video (LDV). This representation consists of one full or central video with associated per-pixel depth and additional residual layers. Thus, only one full view with additional residual data needs to be transmitted. The LDV data is used at the receiver to generate all...
Advanced Multimedia functionalities become an increasingly important element of future mobile devices. The related content however needs to be reproduced on suitable displays. Streaming the video or graphics in "raw" bitmap form will consume enormous bandwidth with respective power consumption and hardware problems. This article presents an approach to render the objects to be displayed...
Most of the needs that occur in applications using subdivision surfaces are covered by our hierarchical mesh data structure. We tested the proposed data structure in some implementations for adaptive visualizations where a highly efficient data structure is essential. Primarily, this means our mesh must support a fast hierarchical refinement of the object with a fast access to the vertices in the...
