示例1: Main
public static void Main(string[] args)
{
Mat src = new Mat("TestImages/2013-12-27-09G37_TRB.jpg", LoadMode.Color);
src = src.Resize (new Size (420, 625));
Mat srcGrey = src.CvtColor(ColorConversion.BgrToGray);
Mat dst = new Mat ();
Point[][] contours;
Mat invertColour = new Mat (src.Rows, src.Cols, src.Type(), new Scalar(255, 255, 255) );
HiearchyIndex[] hierarchy;
Mat contoursLines = new Mat(src.Rows, src.Cols, src.Type());
// InputArray element = Cv2.GetStructuringElement (StructuringElementShape.Ellipse, new Size (16, 16));
// Mat thresh = srcGrey.Threshold (230, 255, ThresholdType.Binary).Dilate(element);
Mat thresh = srcGrey.Threshold (230, 255, ThresholdType.Binary);
Cv2.FindContours (thresh, out contours, out hierarchy, ContourRetrieval.Tree, ContourChain.ApproxSimple);
// Find center of mass in contour
Moments center = Cv2.Moments (contours [0]);
// Convert moment matrix to X/Y coords
