- Abstract:
-
Document layout analysis converts scanned page images into fully searchable text, yet existing research primarily focuses on structured and semi-structured documents. Compared with conventional structured documents, historical documents pose greater challenges due to poor image quality and irregular layouts. To address these issues, we augmented annotations on existing datasets and constructed a multimodal network that integrates textual content, document images, and spatial features. Furthermore, we designed a relation prediction network that combines semantic similarity with spatial adjacency to determine reading order, yielding the final layout analysis result. Our method achieves mean average precision (mAP) scores of 92.4% and 85.6% on the LA-READ and LA-FCR datasets, respectively, with total ordering accuracy (Acc) surpassing previous state-of-the-art results by 3.5% and 2.7%. Experimental results demonstrate the effectiveness of our approach for historical document layout analysis.
