Detail Description

1. Abstract

Optical Character Recognition (OCR) technology enables the extraction of text from images, making it useful for digitizing printed or handwritten content. The AI OCR Image to Text Extractor is a web-based application developed using React.js that allows users to upload images and extract text from them automatically.

This application provides an interface where users can select an image, preview it, and view the extracted text in real time. The system uses API-based OCR processing, and Axios is used for making HTTP requests to retrieve the extracted text.

The project demonstrates the integration of AI-based services with React.js, enabling users to convert images into editable text efficiently.

2. Objectives

The main objectives of this project are:

To develop an AI-based OCR application.
To extract text from images automatically.
To implement React.js for dynamic UI development.
To use Axios for API communication.
To provide real-time image preview and text output.
To create a simple and user-friendly interface.
To demonstrate integration of AI services in web applications.

3. Existing System

Traditional OCR systems include:

• Desktop OCR software

• Online OCR tools with limited free usage

• Mobile apps with restricted features

Limitations of Existing Systems:

Limited accessibility or paid services.
Complex user interfaces in some tools.
Requires installation of software in desktop tools.
Limited customization options.
Less integration with modern web applications.

4. Proposed System

The proposed system is an AI OCR Image to Text Extractor built using React.js.

In this system:

• Users can upload an image through a file selection button.

• The selected image is previewed on the screen.

• OCR processing extracts text from the image.

• Extracted text is displayed in a text box.

• Axios is used to communicate with the OCR API.

This system provides a fast, accessible, and interactive way to convert images into text.

5. Implementation Procedure

Step 1: Project Setup

• Install React.js environment

• Open Command Prompt and create a React app

• Name the application as “OCR Image to Text Application”

Step 2: Development Environment

• Open the project using Visual Studio Code (or any preferred editor)

Step 3: Folder Structure Creation

Inside the src folder, create:

• components – Stores all React components (Uploader, Preview, Output)

• styles – Contains CSS files for styling

Step 4: Dependency Installation

• Install Axios for API requests

Step 5: UI Design

• Create file upload button

• Add image preview section

• Create text display area

Step 6: Image Handling

• Capture selected image

• Display preview on screen

Step 7: OCR API Integration

• Send image data to OCR API using Axios

• Receive extracted text response

Step 8: Display Output

• Show extracted text in text box

• Update dynamically after processing

Step 9: Testing and Execution

• Run the application

• Verify image upload and OCR functionality

• Ensure smooth UI performance

6. Software Requirements

The software tools used in this project include:

• React.js – Frontend library

• JavaScript – Programming language

• Axios – API request handling

• HTML & CSS – UI design

• Visual Studio Code – Code editor

• Node.js & npm – Package management

7. Hardware Requirements

Minimum Hardware Requirements:

• Processor: Intel i3 or higher

• RAM: 4 GB or higher

• Storage: 128 GB or higher

• Laptop or Desktop Computer

8. Advantages of the Project
