Beyond Ground-Truth Fidelity: Rethinking Exposure Correction through Input-Conditioned Perceptual Evaluation

This work challenges ground-truth fidelity as the objective of exposure correction through an input-conditioned human preference study. It introduces ECIQA-Pref, a benchmark of 5,200 images and over 60,000 pairwise judgments, and ECIQA, a degraded-reference quality metric that combines global appearance with native-resolution local structure to evaluate perceptual improvement.
