The most advanced standard for compressing dynamic point clouds, a recently created media format, is video-based point cloud compression (V-PCC). V-PCC relies on creating patches and converting 3D input into 2D frames to apply existing video coding. However, creating patches according to the normals and packing irregular projected patches produce many unoccupied pixels in 2D frames, affecting the temporal prediction and inefficiency of 2D video coding. In addition, unoccupied pixels increase the size of 2D frames, accordingly, the required bitrate. This paper introduces variable-sized hexahedrons segmentation as an alternative to patch creation to reduce the number of unoccupied pixels in the 2D frames. Furthermore, different areas of a point cloud are treated differently according to the density of those areas resulting in capturing points more accurately. This paper investigates combinations of different hexahedrons' sizes, and the experimental results demonstrate that the proposed method with the appropriate hexahedrons' sizes outperforms V-PCC.

Conference2023 IEEE International Conference on Multimedia and Expo Workshops, ICMEW 2023
OtherThe IEEE International Conference on Multimedia & Expo (ICME) has been the flagship multimedia conference for the past two decades. Through the IEEE societies, the Conference serves as a forum to promote the latest advances in multimedia technologies, systems, and applications from both a research and development perspective.

ICME attracts well over 1000 submissions and 500 participants each year, serving as the prime forum for the dissemination of knowledge in the multimedia field. ICME 2023 will showcase high quality oral and poster presentations, as well as feature Workshops sponsored by IEEE societies. Researchers, developers and practitioners are welcomed to organise such Workshops on any new or emerging topic of Multimedia technology. An exposition of multimedia products, animations and industries will be held in conjunction with the conference. Moreover, proposals for Panels, Tutorials, Special Sessions, Industry Technology Workshops and Grand Challenges are also invited. In ICME 2023, exceptional papers and contributors will be also selected and recognised with prestigious awards.
