Unlocking YoloV8 in WinForm Applications: A Step-by-Step Guide for .NET Framework 4.7

Install-Package OpenCVSharp4
Install-Package Emgu.CV
Install-Package YoloV8.NET

Step 2: Load the YoloV8 Model

Once you’ve installed the required libraries and tools, it’s time to load the YoloV8 model. You can do this using the following code snippet:

using YoloV8.NET;

public class YoloV8Loader
{
    public static void LoadModel(string modelPath)
    {
        // Load the YoloV8 model
        YoloV8Model model = new YoloV8Model(modelPath);

        // Initialize the model
        model.Initialize();
    }
}

Step 3: Detect Objects Using YoloV8

Now that you’ve loaded the YoloV8 model, it’s time to use it to detect objects in images or videos. You can do this using the following code snippet:

using OpenCVSharp4;
using Emgu.CV;

public class ObjectDetector
{
    public static void DetectObjects(string imagePath)
    {
        // Read the image using OpenCVSharp4
        Mat image = Cv2.ImRead(imagePath);

        // Convert the image to a format that YoloV8 can use
        byte[] imageData = new byte[image.Rows * image.Cols * 3];
        Marshal.Copy(image.Data, imageData, 0, imageData.Length);

        // Create a YoloV8 detection request
        YoloV8DetectionRequest request = new YoloV8DetectionRequest(imageData, image.Width, image.Height);

        // Detect objects using YoloV8
        YoloV8DetectionResult result = YoloV8.Detect(request);

        // Process the detection results
        foreach (YoloV8Detection detection in result.Detections)
        {
            Console.WriteLine($"Detected object: {detection.ClassName} at ({detection.X}, {detection.Y}) with confidence {detection.Confidence}");
        }
    }
}

Step 4: Integrate YoloV8 into Your WinForm Application

Now that you’ve loaded the YoloV8 model and detected objects using YoloV8, it’s time to integrate YoloV8 into your WinForm application. You can do this by creating a new WinForm and adding a PictureBox control to display the detected objects.

using System.Windows.Forms;

public partial class MainForm : Form
{
    public MainForm()
    {
        InitializeComponent();

        // Load the YoloV8 model
        YoloV8Loader.LoadModel(@"C:\Path\To\YoloV8\Model\File");

        // Set up the PictureBox control
        pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
    }

    private void button1_Click(object sender, EventArgs e)
    {
        // Detect objects using YoloV8
        ObjectDetector.DetectObjects(@"C:\Path\To\Image\File");

        // Display the detected objects in the PictureBox control
        pictureBox1.Image = Image.FromFile(@"C:\Path\To\Image\File");
    }
}

Conclusion

And there you have it, folks! With these simple steps, you can unlock the power of YoloV8 in your .NET Framework 4.7 WinForm application.
