Rate Distortion Modeling For Bit Rate Constrained Point Cloud In this model, we take into account the correlation between geometry and color variables of point clouds and derive a dimensionless quantity to represent the overall quality degradation. then, we derive the relationships of overall distortion and bit rate with the quantization parameters. The rate and distortion models specific for point cloud compression are derived in section iii, in which a unified distortion model is developed to represent the overall quality degradation of point clouds.
Figure 1 From Rate Distortion Modeling For Bit Rate Constrained Point In this model, we take into account the correlation between geometry and color variables of point clouds and derive a dimensionless quantity to represent the overall quality degradation. then, we derive the relationships of overall distortion and bit rate with the quantization parameters. To enhance the efficiency of g pcc without sacrificing its interoperability or computational flexibility, we propose a novel preprocessing framework that integrates a compression oriented. Unlike previous work, our analytical models are functions of the quantization steps of all frames in a group of frames. then, we use our models and an implementation of the differential evolution algorithm to efficiently minimize the distortion subject to a constraint on the bitrate. A unified model to combine the geometry distortion and color distortion of point clouds is proposed and can achieve optimal decoded point cloud quality at various target bit rates, and substantially outperform the video rate distortion model based point cloud compression scheme.

A unified model to combine the geometry distortion and color distortion of point clouds is proposed and can achieve optimal decoded point cloud quality at various target bit rates, and substantially outperform the video rate distortion model based point cloud compression scheme. To address this issue, we propose a distortion propagation model based frame level bit allocation method that is specifically tailored for ai structure in v pcc. To enhance the efficiency of g pcc without sacrificing its interoperability or computational flexibility, we propose a novel preprocessing framework that integrates a compression oriented voxelization network with a differentiable g pcc surrogate model, jointly optimized in the training phase.
