OCRmyPDF adds OCR text layer to scanned PDF files
Just stumbled over this wonderful tool:
github.com/jbarlow83/OCRmyPDF * Generates a searchable PDF/A file from a regular PDF * Places OCR text accurately below the image to ease copy / paste * Keeps the exact resolution of the original embedded images * When possible, inserts OCR information as a "lossless" operation without rendering vector information * Keeps file size about the same * If requested deskews and/or cleans the image before performing OCR * Validates input and output files * Provides debug mode to enable easy verification of the OCR results * Processes pages in parallel when more than one CPU core is available * Uses Tesseract OCR engine * Supports more than 100 languages recognized by Tesseract * Battle-tested on thousands of PDFs, a test suite and continuous integration There is an official package in Debian Linux for those using Linux. I have used it so far to postprocess both a Spanish and English language PDF of my own making, and i am very happy with the results. |
