Treating Point Cloud as Moving Camera Videos: A No-Reference Quality Assessment Metric. (arXiv:2208.14085v2 [cs.CV] UPDATED)

Point cloud is one of the most widely used digital representation formats for
three-dimensional (3D) contents, the visual quality of which may suffer from
noise and geometric shift distortions during the production procedure as well
as compression and downsampling distortions during the transmission process. To
tackle the challenge of point cloud quality assessment (PCQA), many PCQA
methods have been proposed to evaluate the visual quality levels of point
clouds by assessing the rendered static 2D projections. Although such
projection-based PCQA …
