| Summary: | Abstract In this paper, a method for detecting banding artefacts in high‐dynamic‐range (HDR) videos is proposed. The proposed method is the first banding detector designed for HDR videos. To effectively detect banding artefacts, a multi‐scale banding detection strategy based on multiple visual clues is proposed. Specifically, in each scale, the visually perceptual effects of banding artefacts are measured sequentially by luminance, edge strength, and edge length clues. All these clues are exploited by considering the properties of the human vision system and HDR videos. Experimental results show that our method can effectively detect banding artefacts and provide banding visibility maps that highly match the human visual perception. |
