Tibetan Header/Footer (YOLO detection dataset)

This dataset contains page images annotated for header/footer-related page layout elements.

Hosted on Hugging Face: openpecha/Tibetan-header-footer.

Contents

  • Task: object detection
  • Format: YOLO text labels (class x_center y_center width height, all normalized to [0,1])
  • Images: 313 total
    • Train: 251
    • Val: 62
  • Classes (nc=4):
    • 0: header
    • 1: footer
    • 2: footnote
    • 3: page_number

Folder structure

  train/   # .jpg
  val/     # .jpg

How it was produced

Annotations were not created purely by hand from scratch.

  • Step 1 (model inference): bounding boxes were generated by running inference on the page images using:
    • DocLayout-YOLO
    • PP-DocLayout
  • Step 2 (manual correction): the model outputs were then manually corrected using the Ultralytics annotation web app (Ultralytics Hub).

Notes

  • Each image X.jpg has a corresponding label file label/{train|val}/X.txt.
  • Images may contain multiple boxes across classes.
