OCR Annotation

Text transcription and region marking from scans, photographs, and handwriting, including poor-quality sources.

Overview

Transcription from difficult sources - handwriting, low resolution, skewed scans, mixed scripts. Clean documents rarely need a service; the hard inputs are the point.

We handle region marking and reading order alongside transcription, since both matter for downstream extraction.

What you receive

  • Annotated dataset in your training format
  • Written annotation guidelines
  • Quality report with agreement metrics
  • Sample batch for sign-off before volume

Typical stack

  • CVAT
  • Label Studio
  • COCO
  • YOLO
  • Pascal VOC
  • Python

Capabilities

What this covers in practice

01

Written guidelines before volume

Class definitions, edge cases, and rejection criteria agreed and documented before bulk work begins.

02

Calibrated annotator teams

Annotators calibrated against a reference set, with agreement measured before they join a project.

03

Independent review pass

A second annotator reviews sampled output, with rework triggered on defined error thresholds.

04

Delivery in your format

COCO, YOLO, Pascal VOC, or a custom schema - exported to match your existing training pipeline.
