ScalableVideoQualityWithFrameRateAndQuantizationArtifacts

An objective quality metrics that can automatically and accurately measure perceptual video quality is becoming more and more important as video applications become pervasive. Due to the emerge of Scalable Video Coding (SVC), a video steam can be decoded at lower resolution, in terms of temporal, spatial, and SNR. In order to understand the impact of visual quality on temporal and quantization artifacts. it is essential to assess the subjective quality to both quantization and frame rate reduction of videos.

The following are some brief introduction of the test configuration:

  1. The subjective quality is carried out using a protocol similar to ACR (Absolute Category Rating) recommended by ITU-T P.910.
  2. There are 31 viewers participating the test, and a total 20 ratings for each Processed Video Sequence (PVC) after data post-processing.
  3. The testing environment and configurations are carefully followed ITU Recommendation BT.500-11, and ITU_P.910.

For more details of subjective test set up, please refer to the Section II of ITU-R BT.500-11.
