Abstract

This paper deals with two current issues in visual quality assessment, namely, contextual effects in quality judgments and the evaluation of time-varying image quality. A scaling experiment is described showing that contextual effects due to stimulus spacing are negligible when a method based on difference judgments is used. It is also shown that subjects can record their impressions of time-varying image quality by means of moving a slider along a graphical scale. The research on contextual effects as well as on the continuous assessment of time-varying image quality illustrate the important role psychological factors play in image quality evaluation
