Subjective experience of image quality: attributes, definitions, and decision making of subjective image quality

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