Document OCR using Tesseract

This dataset contains OCR results from images in QuarterMill26/k15-europeana using Tesseract, the classical open-source CPU OCR engine — a cheap, no-GPU baseline alongside the VLM OCR recipes.

Processing Details

Configuration

  • Image Column: image
  • Output Column: prediction
  • Dataset Split: train
  • Page Segmentation Mode (psm): 3
  • OCR Engine Mode (oem): 3
  • Workers: 4

Model Information

Tesseract is a classical (non-VLM) OCR engine:

  • Runs on CPU — no GPU required
  • v4+ uses an LSTM-based recognition engine
  • 100+ languages via installable data packs
  • Plain-text output (no markdown / table / formula structure)
  • Apache-2.0 licensed

Dataset Structure

The dataset contains all original columns plus:

  • prediction: The recognised text (plain text)
  • inference_info: JSON list tracking all OCR models applied to this dataset
