本文介绍了一种多视点视频的表示方法，以支持高质量的交互式自由视点绘制运动的人。多个宽基线视图被集成到一个视图相关的表示的基础上成对细化的视觉外壳。提出了一种精确的视相关视觉壳（VDVH）算法来计算场景几何的初始近似。然后使用照片一致性和立体对VDVH表面进行细化。通过前后绘制具有视相关纹理的细化表面，实现了用户控制视点的交互式绘制。结果表明，这种表示实现了高质量的渲染移动的人从宽基线的意见，没有与以前的视觉船体和照片船体的方法相关联的视觉文物。
This paper introduces a representation for multiple view video to support high-quality interactive free-viewpoint rendering of moving people. Multiple wide baseline views are integrated into a view-dependent representation based on pair wise refinement of the visual-hull. An exact viewdependent visual-hull (VDVH) algorithm is presented to compute an initial approximation of the scene geometry. Refinement of the VDVH surface is then performed using photo-consistency and stereo. Interactive rendering with user control of viewpoint is achieved by front-to-back rendering of the refined surfaces with view-dependent texture. Results demonstrate that this representation achieves high-quality rendering of moving people from wide-baseline views without the visual-artefacts associated with previous visual-hull and photo-hull approaches.
