Picture Quality Assessment: A Comparison of Ratio and Ordinal Scales

Metadata

Doc Type: Journal Article
Article Type: research-article
Abstract: Two picture quality experiments were conducted using ratio and ordinal scaling methods. The ratio scales were generated by magnitude estimation and the ordinal scales were rank-ordered category scales. The purpose was to compare the methods to see if one method would outperform the other. Two stimulus ranges were employed on otherwise equivalent stimulus material and observers. The ratio-scale results showed much smaller context effects and have the additional virtue of providing meaningful ratios and intervals in the numerical responses.
