abstract     :  3D video billboard clouds reconstruct and represent a
  dynamic three-dimensional scene using displacement-mapped
  billboards. They consist of geometric proxy planes augmented with
  detailed displacement maps and combine the generality of
  geometry-based 3D video with the regularization properties of
  image-based 3D video. 3D video billboards are an image-based
  representation placed in the disparity space of the acquisition
  cameras and thus provide a regular sampling of the scene with a
  uniform error model. We propose a general geometry filtering
  framework which generates time-coherent models and removes
  reconstruction and quantization noise as well as calibration errors.
  This replaces the complex and time-consuming sub-pixel matching
  process in stereo reconstruction with a bilateral filter.  Rendering
  is performed using a GPU-accelerated algorithm which generates
  consistent view-dependent geometry and textures for each individual
  frame. In addition, we present a semi-automatic approach for
  modeling dynamic three-dimensional scenes with a set of multiple 3D
  video billboards clouds.
