Stop OCRing Every PDF: Route It First with pdf-inspector

Описание и применение

Классифицируйте PDF перед OCR: используйте pdf‑inspector, чтобы извлекать только те страницы, которые действительно требуют распознавания, экономя время и ресурсы.

Задача

OCR is often the most expensive and slowest step in a document-ingestion pipeline, yet many PDFs already contain usable text and are still sent through OCR unnecessarily.

Результат

By classifying PDFs first, the pipeline eliminates unnecessary OCR, saving time and cost while preserving native text structure in Markdown.

Рабочий процесс

• 1. Receive PDF
• 2. Classify PDF and its pages using pdf-inspector
• 3. If PDF is TextBased with high confidence, extract native text locally and convert to Markdown
• 4. If pages lack text or are scanned, route those pages to OCR
• 5. Store or index the resulting Markdown for downstream use
