Learning residual coding for point clouds [PDF]
Recent advancements in acquisition of three-dimensional models have been increasingly drawing attention to imaging modalities based on the plenoptic representations, such as light fields and point clouds. Since point cloud models can often contain millions of points, each including both geometric positions and associated attributes, efficient ...

Point Cloud Object Reconstruction Based on Improved Implicit Function [PDF]
Using an implicit function to reconstruct objects from unstructured point clouds is not limited by topology and resolution, but there are some problems, such as inaccurate structure of reconstructed objects and lack of local details.

Efficient Quadtree Search for HEVC Coding Units for V-PCC
Dynamic point clouds (DPC) are new media storage formats that allow end-users to watch objects/scenes in a three-dimensional (3D) sense. It can be displayed from different angles throughout time.

Point cloud saliency detection via local sparse coding
The human visual system (HVS) can process large quantities of visual information instantly. Visual saliency perception is the process of locating and identifying regions with a high degree of saliency from a visual standpoint. Mesh saliency detection has

GPCGC: A Green Point Cloud Geometry Coding Method
A low-complexity point cloud compression method called the Green Point Cloud Geometry Codec (GPCGC), is proposed to encode the 3D spatial coordinates of static point clouds efficiently. GPCGC consists of two modules. In the first module, point coordinates of input point clouds are hierarchically organized into an octree structure.
