Evaluation of Color Saturation and Hue Effects on Image Quality
2023 International Symposium ELMAR(2023)
Abstract
Saturation and hue are image characteristics that significantly affect the perception of a scene. This paper observes the impact of changing saturation and hue on image quality. Concepts of subjective image quality assessment methods are explained. Reasons for developing objective image quality evaluation methods are provided together with a short overview of the methods used in the paper. A brief interpretation of color spaces in which the objective evaluation was carried out is given. The created image database containing images with modified saturation and hue with regard to original images is described. The settings of the performed subjective testing are stated. A subjective and objective evaluation of image quality was executed. Kendall's tau and Spearman's rho correlation coefficients are calculated for the comparison of subjective and objective evaluation results. Efficiency of the methods is discussed.
