Tesseract OCR Recursive

This script is designed to perform Optical Character Recognition (OCR) on all PDF files within its directory using Tesseract OCR, and outputs the results to a specified output directory. The script leverages ocrmypdf to apply OCR to PDF files, making them searchable and editable.

Features

• Automatically identifies and processes all PDF files in the script's directory.
• Outputs OCR-processed PDFs to a subdirectory named output.
• Utilizes Tesseract OCR for text recognition.

Requirements

• Python 3.x
• ocrmypdf
• Tesseract OCR

Installation

Python Dependencies

To install the required Python dependencies, run the following command:

pip install ocrmypdf

Tesseract OCR

Windows

1. Download the Tesseract installer from the official Tesseract repository.
2. Run the installer and follow the instructions.
3. Add Tesseract to your system PATH:
   • Open the Start Menu and search for "Environment Variables".
   • Click on "Edit the system environment variables".
   • In the System Properties window, click on the "Environment Variables..." button.
   • In the Environment Variables window, find the "Path" variable in the "System variables" section and click "Edit...".
   • Click "New" and add the path to the Tesseract executable (e.g., C:\Program Files\Tesseract-OCR).
   • Click "OK" to close all windows.

Usage

1. Place the script in the directory containing the PDF files you want to process.
2. Run the script using Python:

python Tesseract_OCR_Recursive.py

The script will create an output directory in the same location and save all OCR-processed PDFs there. It will print messages to the console indicating the success or failure of the OCR process for each file.
