IndicSynth-150K
A synthetic document-layout dataset for Indic scripts, generated by the SA-MCB engine (Script-Aware Multi-template Composition Block) for the DocLayout-YOLO-Indic project.
- 150,000 pages (142,500 train / 7,500 val)
- 9 layout classes: text_body, headline, table, figure, caption, advertisement, sidebar, pull-quote, decorative-frame
- 11 Noto fonts, 23 layout templates, 10 Indic scripts + Latin
- Correct Indic shaping via HarfBuzz (conjuncts, stacked matras, shirorekha, RTL for Urdu)
Because each region is placed by the generator, bounding-box labels are exact and require no manual annotation.

Note on findings
In the parent project, pretraining on this corpus did not improve final accuracy over plain fine-tuning (a controlled-ablation finding attributed to catastrophic forgetting). The dataset remains useful for synthetic-data research; see the project for details.
