SIAT-PCQD: Subjective Point Cloud Quality Database
收藏资源简介:
In this paper, we focus on subjective and objective Point Cloud Quality Assessment (PCQA) in an immersive environment and study the effect of geometry and texture attributes in compression distortion. Using a Head-Mounted Display (HMD) with six degrees of freedom, we establish a subjective PCQA database named SIAT Point Cloud Quality Database (SIAT-PCQD). Our database consists of 340 distorted point clouds compressed by the MPEG point cloud encoder with the combination of 20 sequences and 17 pairs of geometry and texture quantization parameters.
本文聚焦沉浸式环境下的主观与客观点云质量评估(Point Cloud Quality Assessment, PCQA),研究几何与纹理属性在压缩失真中的影响。本研究采用具备六自由度的头戴式显示器(Head-Mounted Display, HMD),构建了主观点云质量评估数据库SIAT点云质量数据库(SIAT Point Cloud Quality Database, SIAT-PCQD)。该数据库共包含340组失真点云,均由MPEG点云编码器通过20个原始点云序列与17组几何-纹理量化参数对的组合方式压缩生成。
