Get Choices for Recognized Characters in OCR Image Recognition

Introduction

Unlocking the power of Optical Character Recognition (OCR) is crucial in today’s digital age, and Aspose.OCR for .NET stands out as a robust solution for accurate character recognition. In this tutorial, we’ll delve into a specific feature: obtaining choices for recognized characters. By the end of this guide, you’ll seamlessly integrate this functionality into your .NET applications.

Prerequisites

Before diving into the tutorial, ensure you have the following prerequisites:

  • Basic knowledge of C# and .NET development.
  • Visual Studio installed on your machine.
  • Aspose.OCR for .NET library, which you can download here.

Import Namespaces

In your C# project, start by importing the necessary namespaces:

using System;
using System.Collections.Generic;
using System.Drawing;
using System.IO;
using Aspose.OCR;

Step 1: Initialize Aspose.OCR

Begin by initializing an instance of Aspose.OCR:

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

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

Step 2: Specify Image Path

Set the path for the image you want to analyze:

// Image Path
string fullPath = dataDir + "sample.png";

Step 3: Recognize Image

Execute the image recognition process:

// Recognize image           
RecognitionResult result = api.RecognizeImage(fullPath, new RecognitionSettings
{
    // Default or custom settings
});

Step 4: Get Choices for Recognized Characters

Retrieve choices for recognized characters:

List<char[]> resultWithChoices = result.RecognitionCharactersList;

Step 5: Print the Results

Display the recognition text and choices:

// Print result
Console.WriteLine($"Text:\n {result.RecognitionText}");
Console.WriteLine("Choices:");
resultWithChoices.ForEach(a => Console.WriteLine($"character: {a[0]} . Choices: {a[1]} {a[2]} {a[3]} {a[4]}"));

Console.WriteLine("GetChoiceForRecognizedCharacters executed successfully");

Repeat these steps, customizing them according to your application’s requirements.

Conclusion

In this tutorial, we’ve explored how to leverage Aspose.OCR for .NET to obtain choices for recognized characters in image recognition. This feature adds a new dimension to your OCR capabilities, enhancing the versatility of your applications.
