Banding vs. Quality: Perceptual Impact and Objective Assessment
Lukáš Krasula, Zhi Li, Christos G. Bampis +3
Staircase-like contours introduced to a video by quantization in flat areas, commonly known as banding, have been a long-standing problem in both video processing and quality asses…
VMAF-based Bitrate Ladder Estimation for Adaptive Streaming
Angeliki V. Katsenou, Fan Zhang, Kyle Swanson +3
In HTTP Adaptive Streaming, video content is conventionally encoded by adapting its spatial resolution and quantization level to best match the prevailing network state and display…
Efficient Bitrate Ladder Construction for Content-Optimized Adaptive Video Streaming
Angeliki V. Katsenou, Joel Sole, David R. Bull
One of the challenges faced by many video providers is the heterogeneity of network specifications, user requirements, and content compression performance. The universal solution o…
CAMBI: Contrast-aware Multiscale Banding Index
Pulkit Tandon, Mariana Afonso, Joel Sole +1
Banding artifacts are artificially-introduced contours arising from the quantization of a smooth region in a video. Despite the advent of recent higher quality video systems with m…
Perceptual Video Quality Prediction Emphasizing Chroma Distortions
Li-Heng Chen, Christos G. Bampis, Zhi Li +2
Measuring the quality of digital videos viewed by human observers has become a common practice in numerous multimedia applications, such as adaptive video streaming, quality monito…
