Question

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();

这个程序只在一个图像中找到SIFT描述符。我想与Image进行比较，但我不知道哪个ImageFeature＆lt;＆gt;我会用的。我正在查找ImageFeature的功能＆lt;＆gt;我找不到它请帮我。

Answer 1

ImageFeature []结果包含许多样本，具体取决于图像，每个样本由关键点和描述符（128）组成，这是您要查找的功能。您可以通过例如说result [x] .Descriptor [j]来访问它，x具有样本编号的最大值，j具有最大值128.

在C＃中使用SIFT比较描述符
