Foldr Server

Enabling OCR with AWS Textract

The Foldr server can process and analyse image files and documents containing graphical elements to extract text that is then searchable by users. The Optical Character Recognition (OCR) process can be performed either using the Foldr server’s built-in OCR engine (Tesseract), or cloud OCR engines hosted by AWS (Textract) and Google Vision.
