  13. Gray Scale: Dilation and Erosion Original Dilation: Brighter where small dark details are reduced Erosion: Darker where small bright details are reduced

  14. Gray Scale: Opening and Closing Original Opening: Reduces small bright details with little effect on dark areas. Closing: Reduces small dark details with little effect on bright areas

  15. Smoothing: Opening and then Closing

  16. Gradient: Dilation - Erosion Morphological Edge Detector Direction Independent
