Performance Evaluation of the Codec Agnostic Approach in MPEG-I Video-Based Point Cloud Compression

IEEE Access, 2021
In this study, we evaluated the codec agnostic approach of video-based point cloud compression (V-PCC) by applying several video codecs to V-PCC. The main concept of V-PCC is to use a video codec to compress the 2D patch images generated from a 3D point ...
