Contrast metrics show promise for objectively assessing historical manuscript restoration quality

Researchers have explored the use of contrast-based image quality measures to objectively assess the legibility and quality of reconstructed historical manuscripts. Two experiments using publicly available datasets demonstrated that contrast-based metrics, particularly potential contrast and contrast-to-noise ratio, correlate strongly with expert human ratings and full-reference quality evaluations, respectively. These findings suggest that contrast metrics can serve as reliable indicators for the effectiveness of digital restoration techniques applied to cultural heritage documents. AI

IMPACT This research could lead to more objective and scalable methods for evaluating AI-driven image restoration techniques for historical documents.
