Accurate Mark Detection & Recognition via C# API

A key strength of the open source library OMRMarkEngine lies in its ability to accurately detect and interpret marked regions on scanned images. This is crucial in scenarios where precision is paramount, such as grading exams or analyzing survey responses. The library helps software developers to detect and recognize marked regions with just a couple of lines of C# code. It fully supports multi-page documents, making it suitable for projects involving large volumes of data. Its efficient handling of multiple pages ensures that developers can scale their applications without sacrificing performance. The following example shows how software developers can load and recognize Mark inside C# applications.

How to Perform Mark Detection and Recognition via C# .NET API?

using OMRMarkEngine;
using OMRMarkEngine.Core;

class Program
{
    static void Main()
    {
        // Initialize the OMRMarkEngine
        var omrEngine = new OMRMarkEngine();
        
        // Your code goes here
    }
}
// Load the image
var imagePath = "path/to/your/image.jpg";
omrEngine.LoadImage(imagePath);

// Configure the engine
omrEngine.Config.MarkThickness = 2;
omrEngine.Config.SpacingTolerance = 5;
// Add more configurations as needed

// Define mark regions
omrEngine.AddMarkRegion(new MarkRegion(50, 100, 200, 150)); // Example coordinates

// Process the marked form
omrEngine.Process();

// Extract results
var results = omrEngine.GetResults();

// Display results
foreach (var result in results)
{
    Console.WriteLine($"Mark at coordinates ({result.X}, {result.Y}) detected. Value: {result.Value}");
}

Customization & Easy Integration

One of the OMRMarkEngine library's strengths lies in its flexibility and integration to other .NET applications. Software developers can customize the configuration to adapt the engine to specific requirements. This includes adjusting parameters such as mark thickness, spacing, and alignment to achieve optimal results. The library is designed with ease of integration in mind. The library seamlessly integrates into C# projects, allowing developers to incorporate OMR functionality without the steep learning curve often associated with such specialized tools.
