Document Layout with PP-DocLayoutV3

​Hosted by Isaac Flath and Joe Barrow.

​We’re looking at PP-DocLayoutV3, and specifically how it finds the parts of a document, puts them in reading order, and handles pages that are warped, curved, or rotated.

​We’ll walk through the model and examples from the RT-DocLayout paper, and discuss how we’d use it in document pipelines. Bring questions.

​What we’ll discuss:

• ​Boxes: How it finds and classifies document regions (paragraphs, headings, tables, etc.)

• ​Reading order: How it compares pairs of regions to work out a reading sequence in complex layouts.

• ​Warping and rotation: How the segmentation approach works, and how training sets were created to make it generalize better to distorted pages and curved, warped, and tilted documents.

​Wednesday, October 21, 2026, 7:30–8:30 pm Eastern. Free to join. Register for the calendar invitation and viewing link.
