papyrology

'Date Converter for Ancient Egypt' website code (angularjs)

An open, research-focused tool for the analysis of Papyrus 46

This project uses the lightweight AR framework AR.js to create visualizations for papyri directly in the browser.

Epyrus - Aggregatore di risorse per lo studio dell'Epigrafia e della Papirologia

Text-line phase as an independent sheet-tracking signal for Herculaneum scrolls. Cuts sheet-identity errors 72%/44% on two scrolls, held-out.

Parser for Ancient Greek TEI-XML encoded papyrus texts (https://papyri.info/ | https://github.com/papyri/idp.data) with output optimized for machine learning scenarios (e.g. eScriptorium).

Trace-quality reports for Vesuvius Challenge scroll segments — flags likely segmentation errors from an ink-detection prediction (CPU-only).

Encode Guidelines

Same-winding constraints for the villa spiral fit, derived from published ink detections (PHerc. Paris 4). Preregistered A/B campaign in progress.

Running the Vesuvius spiral fit without the lasagna: umbilicus and dense normals from the CT's structure tensor

Model-free physical ground truth for Vesuvius Challenge surface models: registers the two scroll pairs with a second higher-resolution public scan (PHerc0139 held-out 4.1um, Grand-Prize PHerc1203 2.4um), ships truth labels for both plus a standalone evaluator with shifted-null controls

A calibrated legibility metric over every published Vesuvius Challenge ink prediction: 46,764 equal-area windows, AUC 0.930 against blind labels, and a map of where the pipeline fails.

Audited traced surface geometry on PHerc. MAN5, with the gate that decided what counted and an independent CT check

Chat with Papyri.info IDP data

Certified topology auditing and transverse-clean tifxyz outputs for a five-scroll corpus. Report-only by default; finds where a traced surface passes through itself.
