Quality evaluation is an ever-fascinating field, covering at least a century of research works emerging from psychology, psychophysics, sociology, marketing, medicine, \u2026 While for visual quality evaluation, the ITU Recommendations pave the way towards well-configured, consensual evaluation conditions granting reproducibility and comparability of the experimental results, an in-depth analysis of the state-of-the-art studies shows at least three open challenges, related to the: (1) the continuous vs. discrete evaluation scales, (2) the statistical distribution of the scores assigned by the observers and (3) the usage of semantic labels on the grading scales.<\/p>\n
Thus, we shall present theoretical and methodological results related to:<\/p>\n
1. bridging at the theoretical level the continuous and the discrete scale evaluation procedures and investigating whether the number of the classes on the discrete scales is a criterion meaningful in the results interpretations or just a parameter;<\/p>\n
2. quantifying the bias induced in subjective video quality experiments by the semantic labels (e.g. Excellent, Good, Fair, Poor, and Bad) generally associated to the discrete grading scales;<\/p>\n
3. designing and deploying and experimental test-bed able to support their precision and statistical relevance of the results.<\/p>\n","protected":false},"excerpt":{"rendered":"
