With the increasing demand of compressing and streaming 3D point clouds under
constrained bandwidth, it has become ever more important to accurately and efficiently …

In immersive media communication with point cloud (PC), PC compression will inevitably
cause distortion, which may affect quality of users' visual experience. To monitor the visual …

Video-based point cloud compression (V-PCC) is a state-of-the-art moving picture experts
group (MPEG) standard for point cloud compression. V-PCC can be used to compress both …

In this article, we propose a new distortion quantification method for point clouds, the
multiscale potential energy discrepancy (MPED). Currently, there is a lack of effective …

Point clouds (PCs) have been increasingly applied in business and life, but a variety of PC
transmission and generation systems inevitably produce various types of distortions …

Point clouds are rapidly gaining popularity in many practical applications, and point cloud
quality assessment (PCQA) is an important research topic that helps us measure and …

With the increasing maturity of 3D point cloud acquisition, storage, and transmission
technologies, a large number of distorted point clouds without original reference exist in …

Full-reference point cloud quality assessment (FR-PCQA) aims to infer the quality of
distorted point clouds with available references. Most of the existing FR-PCQA metrics …

Three-dimensional (3D) applications lead the digital transition toward more immersive and
