Abstract
Investigation of image quality on preference and naturalness using 1- dimensional and 2- dimensional colour attributes was performed. Each colour attribute varied in two directions, and each direction had two levels, i.e. large and small. In the present study, paired comparison was employed for image preference and categorical judgement for image naturalness assessment. The aim was to evaluate the performance and effectiveness of 1-dimensional and 2-dimensional colour attributes on image quality. Furthermore, cultural difference, the relationship between image preference and naturalness, the difference between memory colours in colour patches and digital images were examined. The experimental results revealed that the effectiveness of colour attributes on image quality vary with image content.
