Telugu Wikisource OCR — human-verified line crops

1044 single-line crops from Telugu Wikisource page scans, each with a transcription checked against the image by a human. Grayscale, height 64px, width a multiple of 8 — the form the encoder consumes.

Script content

Every line is free of Latin letters — the set is Telugu plus numerals and punctuation. has_english is retained so the filter is auditable, and is False for every row when the dataset is built with DROP_LATIN.

Intended use

Evaluating Telugu line-level OCR. The labels carry no dependence on any particular recogniser, so engines can be compared fairly against them.
