Tesseract is an advanced open-source Optical Character Recognition (OCR) engine that has gained significant popularity due to its robustness, accuracy, and versatility in converting text from images into machine-readable formats. Originally developed by Hewlett-Packard in the 1980s and later maintained by Google, Tesseract has evolved to become one of the most powerful OCR engines available today. It supports a wide range of image formats, including TIFF, PNG, JPEG, and PDF, and can recognize text in multiple languages, with support for over 100 languages, including right-to-left scripts like Arabic and Hebrew, as well as complex languages such as Chinese, Japanese, and Korean.

Tesseract works by analyzing the structure of the image, identifying characters, and applying recognition algorithms to extract the text. It utilizes machine learning and deep learning techniques to improve recognition accuracy over time. While Tesseract is highly effective for printed text, it can also handle handwriting with varying degrees of accuracy, depending on the clarity and consistency of the writing. Its ability to process documents that combine text with images, such as scanned PDFs, makes it useful for document management and archiving solutions.

One of Tesseract’s standout features is its extensibility. Developers can fine-tune the engine for specific use cases by training it with custom datasets, making it ideal for specialized applications where standard OCR models might struggle. Tesseract also provides various output formats, such as plain text, searchable PDFs, and HOCR (HTML-based OCR), which allow for integration into a wide range of software tools and systems.

Furthermore, Tesseract is frequently used in conjunction with other tools and libraries. For instance, it’s often integrated with Python libraries like Pytesseract, enabling quick and easy deployment of OCR capabilities in machine learning and data extraction projects. Tesseract’s open-source nature ensures that it remains free to use, modify, and distribute, making it accessible for developers, researchers, and businesses without incurring licensing fees.

In practical applications, Tesseract is employed in industries such as document scanning, invoice processing, digitization of books, automatic number plate recognition (ANPR), and even in real-time text recognition in augmented reality (AR) applications. Its adaptability and continuous development by an active community ensure that Tesseract remains at the forefront of OCR technology.

To subscribe to this product from Azure Marketplace and initiate an instance using the Azure compute service, follow these steps:

1. Navigate to Azure Marketplace and subscribe to the desired product.
2. Search for “virtual machines” and select “Virtual machines” under Services.
3. Click on “Add” in the Virtual machines page, which will lead you to the Create a virtual machine page.
4. In the Basics tab:

• • Ensure the correct subscription is chosen under Project details.
  • Opt for creating a new resource group by selecting “Create new resource group” and name it as “myResourceGroup.”

5. Under Instance details:

• • Enter “myVM” as the Virtual machine name.
  • Choose “East US” as the Region.
  • Select “Ubuntu 18.04 LTS” as the Image.
  • Leave other settings as default.

6. For Administrator account:

• • Pick “SSH public key.”
  • Provide your user name and paste your public key, ensuring no leading or trailing white spaces.

7. Under Inbound port rules > Public inbound ports:

• • Choose “Allow selected ports.”
  • Select “SSH (22)” and “HTTP (80)” from the drop-down.

8. Keep the remaining settings at their defaults and click on “Review + create” at the bottom of the page.
9. The “Create a virtual machine” page will display the details of the VM you’re about to create. Once ready, click on “Create.”
10. The deployment process will take a few minutes. Once it’s finished, proceed to the next section.

To connect to the virtual machine:

1. Access the overview page of your VM and click on “Connect.”
2. On the “Connect to virtual machine” page:

• • Keep the default options for connecting via IP address over port 22.
  • A connection command for logging in will be displayed. Click the button to copy the command. Here’s an example of what the SSH connection command looks like:
    “`
    ssh [email protected]
    “`

3. Using the same bash shell that you used to generate your SSH key pair, you can either reopen the Cloud Shell by selecting >_ again

or going to https://shell.azure.com/bash.
4. Paste the SSH connection command into the shell to initiate an SSH session.

Usage/Deployment Instructions

Anarion Technologies – Tesseract 

Note: Search product on Azure marketplace and click on “Get it now”

Click on Continue

Click on Create

Creating a Virtual Machine, enter or select appropriate values for zone, machine type, resource group and so on as per your choice.

After Process of Create Virtual Machine. You have got an Option Go to Resource Group 

Click Go to Resource Group

Copy the Public IP Address

SSH into VM Terminal and run these commands:

$ sudo su
$ sudo apt update

$ cd ../..

Verify Installation: 

Open your terminal:

Test with an Image: You can test Tesseract by running it on an image with text. First, ensure you have an image file (e.g., test.png). Then, use the following command to extract text:

$ tesseract test.png output

This will generate a file called output.txt in the same directory. You can check the content of this file to see if Tesseract successfully extracted the text:

$ cat output.txt

If both of these steps work correctly, Tesseract functioning properly on your system.

ThankYou!!!
