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…
Perceptually-inspired super-resolution of compressed videos
Di Ma, Mariana Afonso, Fan Zhang +1
Spatial resolution adaptation is a technique which has often been employed in video compression to enhance coding efficiency. This approach encodes a lower resolution version of th…
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…
Study of Compression Statistics and Prediction of Rate-Distortion Curves for Video Texture
Angeliki V. Katsenou, Mariana Afonso, David R. Bull
Encoding textural content remains a challenge for current standardised video codecs. It is therefore beneficial to understand video textures in terms of both their spatio-temporal…
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…
