摘要:

近十年来,数字人的研究越来越受到人们的关注,人们在数字人的生成、表示、渲染和动画等方面投入了大量的精力。然而,数字人类的质量评估已经落后。因此,为了应对数字人质量评估问题的挑战,我们提出了第一个大规模的三维(3D)扫描数字人头(DHHS)质量评估数据库。所构建的数据库由55个参考DHH和1,540个失真DHH以及主观感知评级组成。然后,一个简单而有效的全参考(FR)投影为基础的方法来评估DHH的视觉质量。该方法采用预先训练好的Swin Transformer tiny进行分层特征提取,利用多头注意力模块进行特征融合。实验结果表明,该方法具有最先进的性能之间的主流FR指标。该数据库公布于https://github.com/zzc-1998/DHHQA。

英文摘要:

Digital humans are attracting more and more research interest during the last decade, the generation, representation, rendering, and animation of which have been put into large amounts of effort. However, the quality assessment of digital humans has fallen behind. Therefore, to tackle the challenge of digital human quality assessment issues, we propose the first large-scale quality assessment database for three-dimensional (3D) scanned digital human heads (DHHs). The constructed database consists of 55 reference DHHs and 1,540 distorted DHHs along with the subjective perceptual ratings. Then, a simple yet effective full-reference (FR) projection-based method is proposed to evaluate the visual quality of DHHs. The pretrained Swin Transformer tiny is employed for hierarchical feature extraction and the multi-head attention module is utilized for feature fusion. The experimental results reveal that the proposed method exhibits state-of-the-art performance among the mainstream FR metrics. The database is released at https://github.com/zzc-1998/DHHQA.
