Full-Reference Image Quality Assessment
Measure perceived quality
with mathematical precision.
UPIQAL synthesizes deep feature statistics, optimal-transport color science, and frequency-domain artifact heuristics into a single interpretable score — with spatially localized diagnostics for blocking, ringing, noise, color shift, and blur.
