In free-viewpoint video, there is a recent trend to represent scene objects as solids rather
than using multiple depth maps. Point clouds have been used in computer graphics for a …

This paper addresses the problem of compression of 3D point cloud sequences that are
characterized by moving 3D positions and color attributes. As temporally successive point …

The rise of capturing systems for objects and scenes in 3D with increased fidelity and
immersion has led to the popularity of volumetric video contents that can be seen from any …

Dynamic point clouds are a potential new frontier in visual communication systems. A few
articles have addressed the compression of point clouds, but very few references exist on …

One of the most important applications in multiview imaging (MVI) is the development of
advanced immersive viewing or visualization systems using, for instance, 3DTV. With the …

We propose using stationary Gaussian processes (GPs) to model the statistics of the signal
on points in a point cloud, which can be considered samples of a GP at the positions of the …

This paper addresses the problem of motion estimation in 3D point cloud sequences that are
characterized by moving 3D positions and color attributes. Motion estimation is key to …

Time-varying mesh, which is attracting a lot of attention as a new multimedia representation
method, is a sequence of 3-D models that are composed of vertices, edges, and some …

In this paper, a novel skeleton-based approach to human time-varying mesh (H-TVM)
compression is presented. The topic of TVM compression is new and has many challenges …

This paper presents keyframe-based geometry video (KGV), a novel framework for
compressing 3-D human motion data by using geometry videos. Given a motion data …
