Domain-Specific Fusion Of Objective Video Quality Metrics

Abstract

iSIZE UK(a) PSNR (b) SSIM (c) VMAF-NEG (d) VMAF (e) Proposed P.910-MOS Figure 1: BD-rate (Bjontegaard Delta-rate) vs. runtime of video encoders when assessed in terms of: PSNR, SSIM, VMAF-NEG, VMAF and the P.910-MOS fused metric derived by our proposal. The utilized encoders (x264 AVC, vpxenc VP9, and svt-av1 AV1, with and without preprocessing) lead to different BD-rate results for each metric. Instead of ad-hoc averaging of BD-rates, we propose to consolidate this difference via domain-specific video quality metric fusion with limited subjective testing.
