Outline of Final Research Achievements

We challenged to construct visual quality criterion by applying the novel evaluation which was focused on a feeling of strangeness. At a relative comparison such as image retouch, the strangeness had common rule of which observers pay attention to unnaturalness point, while there were arbitrary differences among individuals. However, the feeling of strangeness might lead to mistake the criteria because this sensation was affected by overall variation included reference point. The next approach was to add an ill-posed problem to relative evaluation. This problem appeared as the mirror reflection at the case of shape comparison. As the result, an ability of discrimination based on strangeness varied significantly according to a level of recognition. The final examination for strangeness was performed by controlling the CG parameters with absolute memory matching. In this case, it was very difficult to construct visual quality criterion because of the differences among individuals.
