摘要：We analyzed the individual characteristics of visual impressions such as activity (e.g., colorfulness, warmness, contrasty, and waviness), and regularity (e.g., whiteness, regularness, naturalness) depending on perceptual quality scale for JPEG coded images. The individual characteristics of visual impression were grouped into three classes on the basis of similar features where each class characteristics (naturalness - regularity, brightness - complexity) is different based on the values of quality scale changing. The characteristics of an average impression were different from the characteristics of an individual impression. As a result, we focused this study to image quality control based on the individual characteristics of visual impressions.
