Paper Abstract
Subjective quality rating does not reflect the properties of the image directly, but it is the outcome of a quality decision
making process, which includes quantification of subjective quality experience. Such a rich subjective content is often
ignored. We conducted two experiments (with 28 and 20 observers), in order to study the effect of paper grade on image
quality experience of the ink-jet prints. Image quality experience was studied using a grouping task and a quality rating
task. Both tasks included an interview, but in the latter task we examined the relations of different subjective attributes in
this experience. We found out that the observers use an attribute hierarchy, where the high-level attributes are more
experiential, general and abstract, while low-level attributes are more detailed and concrete. This may reflect the
hierarchy of the human visual system. We also noticed that while the observers show variable subjective criteria for IQ,
the reliability of average subjective estimates is high: when two different observer groups estimated the same images in
the two experiments, correlations between the mean ratings were between .986 and .994, depending on the image
content.
