Dual-Attention-Based Block Matching for Dynamic Point Cloud Compression

open access: yesJournal of Imaging
The irregular and highly non-uniform spatial distribution inherent to dynamic three-dimensional (3D) point clouds (DPCs) severely hampers the extraction of reliable temporal context, rendering inter-frame compression a formidable challenge.

Optimized quantization parameter selection for video-based point cloud compression [PDF]

open access: yesFrontiers in Signal Processing
Point clouds are sets of points used to visualize three-dimensional (3D) objects. Point clouds can be static or dynamic. Each point is characterized by its 3D geometry coordinates and attributes such as color.
