OCR-TypeScript-Project

OCR TypeScript Project This project demonstrates how to perform Optical Character Recognition (OCR) using TypeScript. The project integrates Python for image processing tasks using the Tesseract OCR engine and outputs recognized text from various image formats like .jpg and .webp.

Prerequisites

Make sure you have the following installed:

• Node.js
• npm
• Python 3
• Tesseract OCR

Setup

1. Install dependencies:

   • Install Node.js dependencies:

     npm install

   • Create and activate a Python virtual environment:

     python3 -m venv venv
     source venv/bin/activate   # For Linux/Mac
     .\venv\Scripts\activate    # For Windows

   • Install Python dependencies:

     pip install -r requirements.txt

2. Install Tesseract OCR:

   • Follow the installation instructions for your platform.

Running the Project

Running OCR with TypeScript

1. Ensure you are in the project root directory.

2. Compile and run the TypeScript code:

   npx ts-node index.ts

Running OCR with Python

Use the provided Python script for OCR:

python ocr.py

The OCR results will be saved in ocr_output.txt and any processed images will be saved as processed_image.png.

Configuration

The project uses TypeScript and Tesseract for OCR. Modify the index.ts file to change the images being processed. Similarly, the Python script (ocr.py) can be updated for additional image processing logic.

TypeScript Configuration

The project uses a tsconfig.json file for TypeScript settings, ensuring compatibility with modern JavaScript features and Node.js versions.
