Image My_Image = new Image(Openfile.FileName);

            pictureBox1.Image = My_Image.ToBitmap();
            Image<Gray, Byte> modelImage = My_Image.Convert<Gray, byte>();
            SIFTDetector siftCPU = new SIFTDetector();
            VectorOfKeyPoint modelKeyPoints = new VectorOfKeyPoint();


            MKeyPoint[] mKeyPoints = siftCPU.DetectKeyPoints(modelImage, null);
            modelKeyPoints.Push(mKeyPoints);
            ImageFeature<float>[] results = siftCPU.ComputeDescriptors(modelImage, null, mKeyPoints);
            Image<Bgr, Byte> image = Features2DToolbox.DrawKeypoints(modelImage, modelKeyPoints, new Bgr(Color.Red), Features2DToolbox.KeypointDrawType.DEFAULT);
            pictureBox1.Image = image.ToBitmap();

这个程序只是在一张图像中找到 SIFT 描述符。我想与 Image 进行比较，但我不知道我将使用哪个 ImageFeature<>。我正在查找 ImageFeature<> 的功能我找不到它请帮助我。

ImageFeature[] 结果由多个样本组成，具体取决于图像，每个样本由关键点和描述符（128）组成，即您正在寻找的特征。您可以通过例如说 result[x].Descriptor[j] 来访问它，x 具有样本数的最大值，j 具有最大值 128。
