Automated Restoration of Portrait Reliefs in the Binyang Central Cave of the Longmen Grottoes

A novel Gaussian process model-based method achieves high precision and robustness in restoring damaged facial features of the Longmen Grottoes' Imperial Couple's worship reliefs, addressing a critical challenge in cultural heritage preservation. By leveraging surviving samples to learn prior shape knowledge, this approach uses historical photographs and fragments as input data to predict missing portions with experimental validation confirming its accuracy under complex imaging conditions.
