本文介绍了一种新的高清晰度视频质量数据库，简称BVI-HD，其中包含32个参考和384失真视频序列加上主观评分。该数据库中的参考材料经过精心选择，以优化五个低级别视频特征的覆盖范围和分布均匀性，而所包含的12个失真，使用原始高效视频编码（HEVC）和HEVC与合成模式，代表最先进的压缩方法。用于HEVC压缩的数据库中所包含的量化参数的范围由主观研究确定，其结果指示应使用比当前推荐更宽范围的QP值。使用双刺激测试方法，从总共86名受试者中收集了所有384个失真视频的主观意见评分。基于这些结果，我们比较了HEVC和合成内容之间的主观质量，并评估了九种最先进的、完全参考的客观质量指标的性能。该数据库现已在线提供，对那些关注压缩性能评估和客观视频质量评估的人来说是一个宝贵的资源。
This paper introduces a new high-definition video quality database, referred to as BVI-HD, which contains 32 reference and 384 distorted video sequences plus subjective scores. The reference material in this database was carefully selected to optimize the coverage range and distribution uniformity of five low-level video features, while the included 12 distortions, using both original high efficiency video coding (HEVC) and HEVC with synthesis mode, represent state-of-the-art approaches to compression. The range of quantization parameters included in the database for HEVC compression was determined by a subjective study, the results of which indicate that a wider range of QP values should be used than the current recommendation. The subjective opinion scores for all 384 distorted videos were collected from a total of 86 subjects, using a double stimulus test methodology. Based on these results, we compare the subjective quality between HEVC and synthesised content, and evaluate the performance of nine state-of-the-art, full-reference objective quality metrics. This database has now been made available online, representing a valuable resource to those concerned with compression performance evaluation and objective video quality assessment.
