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 ...

3D Motion Estimation and Compensation Method for Video-Based Point Cloud Compression
IEEE Access, 2020 A point cloud visualizes information by placing a voxel with a color value and a position value in a three-dimensional space. Since a point cloud uses hundreds of thousands or millions of points to visualize information, a large number of bits is needed ...

Video Coding Using 3D Dual-Tree Wavelet Transform
EURASIP Journal on Image and Video Processing, 2007 This work investigates the use of the 3D dual-tree discrete wavelet transform (DDWT) for video coding. The 3D DDWT is an attractive video representation because it isolates image patterns with different spatial orientations and motion directions and ...

Perceptually-driven video coding with the Daala video codec [PDF]
SPIE Proceedings, 2016 The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video codecs with alternative approaches, many of them designed to take perceptual aspects into account, rather than optimizing for simple metrics like PSNR.

Impact of Constant Rate Factor on Objective Video Quality Assessment
Advances in Electrical and Electronic Engineering, 2017 This paper deals with the impact of constant rate factor value on the objective video quality assessment using PSNR and SSIM metrics. Compression efficiency of H.264 and H.265 codecs defined by different Constant rate factor (CRF) values was tested.
