Alternative Half-Sample Interpolation Filters for Versatile Video Coding

Anastasia Henkel, Ivan Zupancic, Benjamin Bross, Martin Winken, Heiko Schwarz, Detlev Marpe +1

ICASSP 2020accepted

To reduce the residual energy of a video signal, motion compensated prediction with fractional-sample accuracy has been successfully employed in modern video coding technology. In contrast to the fixed quarter-sample motion vector resolution for the luma component in High Efficiency Video Coding sta…

Xpsnr: A Low-Complexity Extension of The Perceptually Weighted Peak Signal-To-Noise Ratio For High-Resolution Video Quality Assessment

Christian R. Helmrich, Mischa Siekmann, Sören Becker, Sebastian Bosse, Detlev Marpe, Thomas Wiegand

ICASSP 2020accepted

The objective PSNR metric is known to correlate quite poorly with subjective assessments of video coding quality. Thus, a number of alternative VQA measures such as (MS-)SSIM and VMAF have been proposed. These, however, are often algorithmically complex and difficult to use for visually motivated en…
