Frame rate versus spatial quality: Which video characteristics do matter?

Several studies have shown that the relationship between perceived video quality and frame rate is dependent on the video content. In this paper, we have analyzed the content characteristics and compared them against the subjective results derived from preference decisions between different spatial and temporal quality levels. We also propose simple yet powerful metrics for characterizing spatial and temporal properties of a video sequence, and demonstrate how these metrics can be applied for evaluating the relative impact of spatial and temporal quality on the perceived overall quality.
