Check out the answer to the following question:

watershed function provided by EmguCv

You need to set the values of the mask file to zero (use cvZero for that). Use a second reference circle (preferably with a different greyvalue) and then retrieve the result from your mask file, after converting it to a greyvalue image.

Here is some vanilla code that makes use of watershed function on a generic input image using emgucv:

public void TestWaterShed()
          {  
             Image<Bgr, Byte> image = new Image<Bgr, byte>("myImage.jpg");                 
             Image<Gray, Int32> marker = new Image<Gray, Int32>(image.Width, image.Height);
             Rectangle rect = image.ROI;
             marker.Draw(
                new CircleF(
                   new PointF(rect.Left + rect.Width / 2.0f, rect.Top + rect.Height / 2.0f),
                   (float)(Math.Min(image.Width, image.Height) / 4.0f)),
                new Gray(255),
                0);
             CvInvoke.cvWatershed(image, marker);
          }
