用3张标注图实现古籍手写行分割,降低人工标注负担
ICDAR 2025 Competition on FEw-Shot Text line segmentation of ancient handwritten documents (FEST)
- 基于三张标注图像的少样本学习方法
- 在复杂布局与退化文本上实现稳定分割
- 适合人文学者快速部署古籍分析工具
文本行分割是手写文档图像分析的关键步骤。由于手写风格不规则、墨迹褪色及文本行重叠、非线性排布等复杂问题,古籍手写文档的文本行分割面临独特挑战。此外,大规模标注数据集稀缺,使全监督学习难以应用。为此,我们发起古籍手写文档少样本文本行分割(FEST)竞赛。参赛者需在仅提供每份手稿3张标注图像的条件下,对U-DIADS-TL数据集进行文本行分割。该数据集包含多样化的古籍手稿,涵盖广泛布局、退化程度和非标准格式,真实反映实际研究场景。通过强调少样本学习,FEST竞赛旨在推动高效、鲁棒且可适应性强的方法发展,使人文学者以极少的人工标注投入即可使用自动化文档分析工具,促进历史研究中技术的广泛应用。
原文摘要 · Abstract (English)
Text line segmentation is a critical step in handwritten document image analysis. Segmenting text lines in historical handwritten documents, however, presents unique challenges due to irregular handwriting, faded ink, and complex layouts with overlapping lines and non-linear text flow. Furthermore, the scarcity of large annotated datasets renders fully supervised learning approaches impractical for such materials. To address these challenges, we introduce the Few-Shot Text Line Segmentation of Ancient Handwritten Documents (FEST) Competition. Participants are tasked with developing systems capable of segmenting text lines in U-DIADS-TL dataset, using only three annotated images per manuscript for training. The competition dataset features a diverse collection of ancient manuscripts exhibiting a wide range of layouts, degradation levels, and non-standard formatting, closely reflecting real-world conditions. By emphasizing few-shot learning, FEST competition aims to promote the development of robust and adaptable methods that can be employed by humanities scholars with minimal manual annotation effort, thus fostering broader adoption of automated document analysis tools in historical research.
