How to modify datatype of Matrix<float> to array?

问题

I am using Emgu CV (v2.4) with C#. In the following class. I need to modify the data type of the used column in the table to array.

public void  FindSURF(Image<Gray, Byte> modelImage)
{
    VectorOfKeyPoint modelKeyPoints;

    SURFDetector surfCPU = new SURFDetector(500, false);

    //extract features from the object image
    modelKeyPoints = new VectorOfKeyPoint();
    Matrix<float> modelDescriptors = surfCPU.DetectAndCompute(modelImage, null, modelKeyPoints);

}  

the SURF feature extract and store in Matrix<float> modelDescriptors how can I modify this datatype to array?

回答1:

You could use the property from the Matrix:

float[] elements = modelDescriptors.Elements;
