我们评估了三种最先进的视频编解码器在合成视频上的性能。评估基于主观和客观质量指标。压缩视频序列的主观质量使用双刺激损伤量表（DSIS）评估指标进行评估，而峰值信噪比（PSNR）用于客观评估。进行了大量的实验来研究帧速率和分辨率对合成视频编解码器性能的影响。评估结果表明，视频编解码器对帧速率和帧分辨率变化的响应方式不同。与其他编解码器相比，H.264 显示出卓越的功能。显示各种比特率、帧速率和帧分辨率的平均意见得分 (MOS) 结果。
We evaluate the performance of three state of the art video codecs on synthetic videos. The evaluation is based on both subjective and objective quality metrics. The subjective quality of the compressed video sequences is evaluated using the Double Stimulus Impairment Scale (DSIS) assessment metric while the Peak Signal-to-Noise Ratio (PSNR) is used for the objective evaluation. An extensive number of experiments are conducted to study the effect of frame rate and resolution on codecs’ performance for synthetic videos. The evaluation results show that video codecs respond in different ways to frame rate and frame resolution change. H.264 shows superior capabilities compared to other codecs. Mean Opinion Score (MOS) results are shown for various bitrates, frame rates and frame resolutions.
