Understanding Transformer-Based OCR for Medieval Manuscripts: A Systematic Ablation Study and Inspection Analysis

2025-12-04

Abstract excerpt

<title>Abstract</title> <p>Adapting Transformer-based Optical Character Recognition (TrOCR) models to medieval manuscripts presents a significant domain gap. This work provides a systematic investigation into TrOCR fine-tuning strategies using a 14th-15th century Italian manuscript. We conduct controlled ablation studies on preprocessing, data augmentation, and encoder layer freezing. Results demonstrate that ful...
