Abstract

Banding, a common video quality artifact, it refers to the noticeable gradient steps or abrupt transitions between adjacent colors or shades within an image or video, often as a resulting from low color depth or compression algorithms. Assessing banded video quality is vital, especially with the rise of high-quality screens. Several banding metrics have been proposed in recent years to quantify and evaluate the presence of banding artifacts in videos. However, the visibility of banding strongly depends on viewing conditions such as screen brightness, contrast, ambient lighting, and others. This results in inconsistencies in the correlation between banding metrics and the subjective quality perceived across various screens. In this study, we conduct subjective experiments under varied viewing conditions and demonstrate the limited reliability of banding metrics
