本文比较了两种主观评价方法DSCQS（双刺激连续质量量表法）和ACR（绝对类别评分法）。这些方法被广泛用于评估多媒体应用中的视频质量。我们使用DSCQS和ACR方法进行主观质量测试。由DSCQS和ACR方法获得的主观分数表明，这些方法在MOS（平均意见分数）方面具有高度相关性，在DMOS（差异平均意见分数）方面具有较低的相关性。结果表明，ACR方法是一种有效的主观质量评价方法，与DSCQS方法性能相当，可以评价更大数量的视频序列。
In this paper, we compared two subjective assessment methods DSCQS(Double Stimulus Continuous Quality Scale method) and ACR(Absolute Category Rating). These methods are widely used in order to evaluate video quality for multimedia application. We performed subjective quality tests using DSCQS and ACR methods. The subjective scores obtained by the DSCQS and ACR methods show that these methods are highly correlated in terms of MOS(Mean Opinion Score) and have slightly lower correlation in terms of DMOS(Difference Mean Opinion Score). The results indicate that ACR method is an effective subjective quality assessment method, which shows compatible performance with DSCQS method and can evaluate a larger number of video sequences.
