Morphological filtering:
min/max graylevel morphological filter is equivalent to
Opening
Morphological filtering:
max/min graylevel morphological filter is equivalent to
Closing
Removal of small object holes (dilation then erosion)
Closing -> max then min
Removal of small background holes (erosion then dilation)
Opening -> min then max
The local _ of the Laplacian of an image helps to detect its edges
Minimum
Erosion =
Dilation of complement
Dilation =
Erosion of complement
