Returns a structing element of the specified size and shape for morpholigical operations
Parameters
- shape
- Type: Emgu.CV.CvEnum.ElementShape
Element shape - ksize
- Type: System.Drawing.Size
Size of the structuring element. - anchor
- Type: System.Drawing.Point
Anchor position within the element. The value (-1, -1) means that the anchor is at the center. Note that only the shape of a cross-shaped element depends on the anchor position. In other cases the anchor just regulates how much the result of the morphological operation is shifted. - ===============================================
