如何訪問興趣點的哈里斯角點檢測的C＃

Question

我執行使用Emgucv 哈里斯角探測器，我已經使用這個鏈接

http://docs.opencv.org/doc/tutorials/features2d/trackingmotion/harris_detector/harris_detector.html 所以我想訪問的座標轉換的代碼轉換爲C＃ 那些角落或任何有關這個興趣點的信息 如何做到這一點？ 謝謝

您可以製作哈里斯角圖像的閾值圖像，然後遍歷它。這種方式是點的強度是255你有一個角點惠特X和Y值在圖像上。示例：

 // create corner strength image and do Harris 
    m_CornerImage = new Image<Gray, float>(m_SourceImage.Size); 
     CvInvoke.cvCornerHarris(m_SourceImage, m_CornerImage, 3, 3, 0.01); 

     // create and show inverted threshold image 
     m_ThresholdImage = new Image<Gray, Byte>(m_SourceImage.Size); 
     CvInvoke.cvThreshold(m_CornerImage, m_ThresholdImage, 0.0001, 255.0, Emgu.CV.CvEnum.THRESH.CV_THRESH_BINARY_INV); 
     imageBox2.Image = m_ThresholdImage; 
     imageBox1.Image = m_CornerImage; 

     const double MAX_INTENSITY = 255; 
     int contCorners = 0; 
     for (int x = 0; x < m_ThresholdImage.Width; x++) 
     { 
      for (int y = 0; y < m_ThresholdImage.Height; y++) 
      { 
       Gray imagenP = m_ThresholdImage[y,x]; 
       if (imagenP.Intensity == MAX_INTENSITY) 
       { 
        //X and Y are harris point cordenates 
       } 
      } 
     }
