Comparison of blocking and blurring metrics for video compression
Athanasios Leontaris, Amy R. Reibman · 2006
We evaluate the performance on compressed video of a number of available similarity, blocking, and blurring quality metrics. Using a systematic, objective framework based on simple subjective comparisons, we evaluate the ability of each metric to rank images correctly according to the subjective impact of differences in spatial content, quantization parameters, amounts of filtering, distances from the most recent I-frame, and long-term frame prediction strategies. The indicated weaknesses of available metrics can be used as guides in the development of future quality metrics.
