ATTEMPTS TO DIMINISH UNCERTAINTY IN QUALITY EVALUATION OF COMPRESSED VIDEO BY HUMAN AUDIENCE

• Abstract:

  The paper concerns one of subjective continuous quality evaluation method (SSCQE), which is used for measuring the human perception of compression errors in video. The problem with subjective quality assessment is a big measurement uncertainty that makes drawing conclusions on quality of compared materials with required significance level difficult. The paper presents a new method of measurement data processing, which enables for decreasing the unwanted influence of human factors and diminishing the standard deviation of the measurement results by a half. The Mandel's h and k statistics are used, likewise in inter-laboratory comparisons programs.
