Extraction
The extraction phase consists of reading the PDF document and gather text blocs, along with their dimensions and position within the document. Said blocs will go on to the classification phase to separate the body from the rest.
Text-based PDF
We provide a multiple extractor architectures for text-based PDFs :
| Component | Description |
|---|---|
| pdfminer-extractor | Text-based PDF extraction using PDFMiner |
| mupdf-extractor | Text-based PDF extraction using MuPDF |
| poppler-extractor | Text-based PDF extraction using Poppler |
Image-based PDF
Image-based PDF documents require an OCR1 step, which is not natively supported by EDS-PDF. However, you can easily extend EDS-PDF by adding such a method to the registry.
We plan on adding such an OCR extractor component in the future.
