Manipulating Scanned PDF Files
Explore how to use Python to manipulate scanned PDF files by applying Optical Character Recognition (OCR). Understand the process of converting scanned images to editable text, highlighting or redacting content, and managing page processing with Python libraries such as Pytesseract, OpenCV, and PyMuPDF. This lesson equips you with skills to handle scanned PDFs for real-world applications including document analysis and data extraction.
Introduction
PDF documents are mainly created in two different ways. They are either generated by an electronic source, known as a native PDF, or by scanning in paper documents, known as a scanned PDF.
Native PDF documents contain an internal structure that can be read and interpreted, whereas scanned PDFs consist of scanned images, meaning that their content cannot be searched or edited.
