Recognize Image from Stream in OCR Image Recognition

Introduction

Welcome to the exciting realm of optical character recognition (OCR) using Aspose.OCR for .NET! Whether you’re a seasoned developer or just diving into the world of OCR, this step-by-step guide will walk you through recognizing images from streams effortlessly. Aspose.OCR for .NET is a robust tool that enables seamless integration of OCR functionality into your .NET applications, making text extraction from images a breeze.

Prerequisites

Before we embark on this OCR journey, make sure you have the following prerequisites in place:

• Aspose.OCR for .NET Library: If you haven’t already, download and install the library from the Aspose.OCR for .NET Documentation.

• Sample Image: Prepare a sample image (let’s call it “sample.png”) that you want to recognize. Ensure it’s in a readable format for the OCR process.

Import Namespaces

To get started, include the necessary namespaces in your project:

using System;
using System.IO;
using Aspose.OCR;

Now, let’s break down the example into multiple steps.

Step 1: Set Document Directory

// The path to the documents directory.
string dataDir = "Your Document Directory";

Ensure to replace “Your Document Directory” with the actual path to your document directory.

Step 2: Initialize Aspose.OCR

// Initialize an instance of AsposeOcr
AsposeOcr api = new AsposeOcr();

Create an instance of the AsposeOcr class to leverage the OCR functionality.

Step 3: Recognize Image from Stream

// Recognize image
using (MemoryStream ms = new MemoryStream())
using (FileStream file = new FileStream(dataDir + "sample.png", FileMode.Open, FileAccess.Read))
{
    file.CopyTo(ms);
    result = api.RecognizeImage(ms);
}

This step involves opening the image file from the specified path, converting it into a MemoryStream, and then using the AsposeOcr instance to recognize the text.

Step 4: Display the Recognized Text

// Display the recognized text
Console.WriteLine(result);

Output the recognized text to the console or store it as needed.

Step 5: Execution Success Message

Console.WriteLine("RecognizeImageFromStream executed successfully");

Provide a confirmation message to indicate the successful execution of the image recognition process.

Conclusion

Congratulations! You’ve successfully harnessed the power of Aspose.OCR for .NET to recognize text from images. The ease of integration and robustness of this library make it a go-to solution for OCR tasks in your .NET applications.
