如何在C#中调用Sobel滤波器、图像处理函数

using Emgu.CV;
using Emgu.CV.CvEnum;
using Emgu.CV.Structure;

public class ImageProcessing
{
    public static Image<Gray, byte> ApplySobelFilter(Image<Gray, byte> image)
    {
        // Convert the image to grayscale if it's not already
        if (image.NumberOfChannels > 1)
            image = image.Convert<Gray, byte>();

        // Apply Sobel filter
        Image<Gray, float> sobelImage = image.Sobel(1, 0, 3);

        // Convert the result back to byte format
        Image<Gray, byte> result = sobelImage.Convert<Gray, byte>();

        return result;
    }
}

public class Program
{
    public static void Main()
    {
        // Load an image
        Image<Bgr, byte> originalImage = new Image<Bgr, byte>("path/to/image.jpg");

        // Convert the image to grayscale
        Image<Gray, byte> grayImage = originalImage.Convert<Gray, byte>();

        // Apply Sobel filter
        Image<Gray, byte> sobelImage = ImageProcessing.ApplySobelFilter(grayImage);

        // Display the original and processed images
        CvInvoke.Imshow("Original Image", originalImage);
        CvInvoke.Imshow("Sobel Filter Result", sobelImage);
        CvInvoke.WaitKey(0);
    }
}
