Subjective Quality Database and Objective Study of Compressed Point Clouds With 6DoF Head-Mounted Display

In this paper, we focus on subjective and objective Point Cloud Quality Assessment (PCQA) in an immersive environment study the effect of geometry texture attributes compression distortion. Using a Head-Mounted Display (HMD) with six degrees freedom, establish PCQA database, named SIAT Database (SIAT-PCQD). Our database consists 340 distorted point clouds compressed by MPEG cloud encoder combination 20 sequences 17 pairs quantization parameters. The impact is further discussed paper. Then, propose two projection-based quality evaluation methods, i.e., weighted view projection based model patch model. findings can be used processing, transmission, coding, especially for virtual reality applications. dataset https://dx.doi.org/10.21227/ad8d-7r28 xmlns:xlink="http://www.w3.org/1999/xlink">http://codec.siat.ac.cn/video_download_siat-pcqd.htmlhas been released public repository.
