February 2018 | NTIA Technical Memo TM-18-532
This report describes the video quality subjective test its4s, including the experiment design and footage attribution. Subjective experiment its4s includes 813 unique video sequences, each four seconds in duration. No video sequences are repeated. The goals are (1) to provide insights into the optimal experiment designs for training no-reference (NR) metrics, and (2) to understand the impact of original video quality on mean opinion scores (MOS). Together these goals support the larger goal of progressing research on effective NR metrics. The dataset is freely available for research and development purposes.
Videos and ratings can be found on CDVL (www.cdvl.org) by doing a keyword search for "its4s".
Keywords: video quality; image quality; subjective testing
