3D video fragments: dynamic point samples for real-time free-viewpoint video

3D video fragments: dynamic point samples for real-time free-viewpoint video

We present 3D video fragments, a dynamic point sample framework for real-time 3D video. By generalizing 2D video pixels towards 3D irregular point samples we combine the simplicity of conventional 2D video processing with the power of more complex polygonal representations for 3D video. We propose a differential update scheme exploiting the spatio-temporal coherence of the video streams of mult...

Dynamic Point Samples for Free-viewpoint Video

Free-viewpoint video (FVV) uses multiple video streams to rerender a time-varying scene from arbitrary viewpoints. FVV enables free navigation with respect to time and space in streams of visual data and allows for virtual replays and for freeze-androtate effects, for instance. Moreover, FVV technology can improve communication between remote participants in high-end telepresence applications. ...

Real-time Free-viewpoint Video Based on 3D Shape Reconstruction

In this paper, we present a system generating free-viewpoint video in real-time using multiple cameras and a PC-cluster. Our system firstly reconstructs a shape model of objects by the visual cone intersection method, secondly transforms the shape model represented in terms of a voxel form into a triangular patch form, thirdly colors vertexes of triangular patches, and finally displays the shap...

Real-time microfacet billboarding for free-viewpoint video rendering

We present a hardware-accelerated method for video-based rendering relying on an approximate model of scene geometry. Our goal is to render high-quality views of the scene from arbitrary viewpoints in real-time, using as input synchronized video-streams from only a small number of calibrated cameras distributed around the scene. Despite the fact that only a very coarse geometry reconstruction i...
