Layout Analysis
A core task in the document intelligence field: identifying regions such as text blocks, images and tables from page images or PDF coordinate information and inferring their logical relationships and reading order.
Timeline (last 90 days)
The root cause of fixed-coordinate splitting failing is that it assumes a fixed layout, whereas the layout of real academic PDFs varies page by page and even block by block.
The output of general-purpose OCR engines is usually just text fragments with coordinates, and does not understand layout semantics, requiring layout analysis to determine the hierarchical relationships of paragraphs, tables, and headings.
Layout analysis divides a page into semantic regions such as heading areas, body text areas, caption areas, and headers/footers, and is a prerequisite step for parsing multi-column PDFs, academic papers, or financial reports.
