1. Mat AAA = Cvinvoke.getstructuringelement (Emgu.CV.CvEnum.ElementShape.Rectangle, new Size (5, 5), new Point (2, 2)  );
2. Imagebox1.image = A.morphologyex (Emgu.CV.CvEnum.MorphOp.Tophat, AAA, New Point (1, 1), 1,  Emgu.CV.CvEnum.BorderType.Default, new Mcvscalar (255, 0, 0, 255));

Where the mat class above is used to define the size and shape of the kernel, in general, the value in size is twice times plus 1 for the point.

1. Open

Open operation is to the image first corrosion and then expand, you can exclude small groups of the object conversion formula is:

: (pictured on the left)

2.Close

Closed operation is the first expansion of the image and then corrosion, can be ruled out small black holes, the transformation of the formula:

3, Gradient

Return the picture is the difference between the expansion chart and the corrosion diagram, you can retain the edge contour of the object, the transformation formula is:

: (pictured on the left)

4, Tophat

The return image is the difference between the original image and the open operation result graph, and the transformation formula:

: (pictured on the left)

5, Blackhat

Returns the difference between the closed operation result graph and the original image, and the transformation formula is:

: (pictured on the left)
