Research and Proposal of 3D Domain Processing Techniques in Woodblock Model Restoration

Abstract

Vietnamese historical printing woodblock, engraved with Han or Nom characters, have earned UNESCO recognition as World Documentary Heritage. However, after hundreds of years, the number of these woodblocks is gradually diminishing due to loss or damage over time. This poses the challenge of restoring the 3D digital model of these woodblocks based on the remaining imprints on traditional paper. In the execution of this restoration task, 3D processing techniques play a pivotal role, determining the final quality of the restored 3D models. Current 3D processing techniques often fall short when applied to woodblock due to the intricate manual carving process that imparts a distinct cultural essence to each plate. In this work, we delve into the research and propose 3D processing techniques tailored for the restoration of 3D models from 2D imprints. These techniques have been integrated to form a comprehensive 3D processing pipeline for the woodblock restoration task.
In the experimentation, we conducted an evaluation of the the effectiveness of our proposed methods. The result showed that these techniques are appropriate and contribute to addressing the restoration problem.
