I have the following code:

public static Image<Gray, byte> Segmentation(Image<Gray, byte> Image)
 
 Image<Gray, byte> Image2 = new Image<Gray, byte>(Image.Size);
 Image2 = Image.Clone();

 Image<Gray, float> edges = new Image<Gray, float>(Image2.Size);
 VectorOfVectorOfPoint contours = new VectorOfVectorOfPoint();
 Image<Gray, float> hierarchy = new Image<Gray, float>(Image2.Size);
 Image<Gray, byte> ContourImage = new Image<Gray, byte>(Image2.Size);

 CvInvoke.Canny(Image2, edges, 100, 200);
 CvInvoke.FindContours(edges, contours, hierarchy, RetrType.Tree, ChainApproxMethod.ChainApproxNone);
 CvInvoke.DrawContours(ContourImage, contours, -1, new MCvScalar(255, 255, 255), 1, LineType.EightConnected);

 MCvMoments moments = CvInvoke.Moments(ContourImage);
 Point WeightedCentroid = new Point((int)(moments.M10 / moments.M00), (int)(moments.M01 / moments.M00));
 ContourImage.Data[WeightedCentroid.Y, WeightedCentroid.X, 0] = 255;

 CvInvoke.Imshow("Contour", ContourImage);

 int height = ContourImage.Rows;
 int width = ContourImage.Cols;
 Mat outputMask = new Mat(height + 2, width + 2, DepthType.Cv8U, 1);
 Rectangle dummy = new Rectangle();
 CvInvoke.FloodFill(ContourImage, outputMask, WeightedCentroid, new MCvScalar(255), out dummy,
 new MCvScalar(0), new MCvScalar(0), Connectivity.EightConnected, FloodFillType.MaskOnly);

 CvInvoke.Imshow("Contour", ContourImage);

 Image<Gray, byte> Image3 = new Image<Gray, byte>(ContourImage.Size.Width, ContourImage.Size.Height, new Gray(0));

 return Image3;
 

The code above should detect human body contour, calculate the center point and then fill it with white color, but the contour did not filled as expected. What is the problem of my code please?
