Line labelling guide (HTR ground truth)

Labels pair one refined line crop (training/line_proposals_v2.json, images in training/proposals_v2/) with the exact text visible in it. Batches go in training/labels/batch_NNN_<row>.json and are merged with pipeline/merge_labels.py. See that script’s docstring for the format.

Crops

pipeline/refine_lines.py extends each cell line so words that run across a printed column rule stay whole. Ink belonging to neighbouring cells is painted with the recorded paper colour (mask_fill); the export verifies that only those pixels differ from the scan. A crop never contains half a glyph, but it can contain:

• a whole stray glyph or punctuation from a neighbouring cell (e.g. the comma after a child’s name appearing at the start of the parents line). Transcribe it: it is visible text.
• specks and flourishes that are not characters. Do not transcribe them; say so in note.

Reject (rejected_crop) strips with only rules, flourishes, junk, two merged text lines, or a glyph visibly cut by the top/bottom edge in a way that hides its identity.

Transcription (diplomatic)

• Pre-1918 letters exactly as written: ъ, ѣ, і. Do not modernize, and do not add a letter the clerk omitted.
• In the later hand (spreads ~111+), ѣ looks like a tall к (“Апрѣля”, “Костелѣ”). In the early hand (≤ ~100), т is written like m and line-end hyphens are often a double stroke, transcribed =.
• Line-end/line-start hyphens and filler dashes as written (три-, -бли, Прихода. -).
• Superscripts inline: 12го, 23го. Underlining is not transcribed.
• Capitals and punctuation as written, including 1888. if dotted.
• Single spaces between words; when spacing is ambiguous, follow the word division.

Status

• image_checked: every character read with confidence. Exported for training and evaluation. One reader only: this is not independent verification.
• draft: any doubt. Mark it inline: [Г?]елена, [Бекешіовъ?]. Never exported. Names, villages and townships are usually drafts until a second source confirms them.
• Seeing the baseline model’s output is recorded in the batch (baseline_seen). Treat it as a hint only. It modernizes spelling (drops ъ, writes е for ѣ).

Known formula (for orientation, not for filling in unseen text)

Baptism: Тысяча восемьсотъ восемьдесятъ восьмаго года [месяц] [день] дня, въ Плунгянскомъ Р.К. Приходскомъ Костелѣ Викарнымъ Кс: [priest] окрещенъ младенецъ именемъ [NAME] со всѣми обрядами Таинства. Parents: Крестьянъ [township] волости [father] и [mother] изъ [maiden] [surname] законныхъ супруговъ сынъ/дочь родившійся/родившаяся 1888 года [month] [day] дня въ деревнѣ [village] сего Прихода. Godparents: Воспріемниками были [name surname] съ [name surname] [status].

The clerk’s actual wording varies (e.g. деревни, Яна и Францишки). Transcribe what is written, never what the formula predicts.
