MorphologicalPerimeter

MorphologicalPerimeter[image]

picks out the morphological perimeter of regions of foreground in image.

MorphologicalPerimeter[image,t]

treats values above t as foreground.

Details and Options

  • Morphological perimeter is defined to consist of foreground pixels that are directly adjacent to the background.
  • MorphologicalPerimeter works with arbitrary 2D and 3D images, as well as real arrays of any rank.
  • MorphologicalPerimeter[image,…] yields a binary image in which pixels considered to be on the morphological perimeter have value 1 and others have value 0.
  • MorphologicalPerimeter[image] is equivalent to MorphologicalPerimeter[image,0].
  • The following options can be specified:
  • CornerNeighbors Truewhether to include corner neighbors
    Padding 0padding method

Specify an intensity threshold:

Options  (3)

CornerNeighbors  (2)

In 2D, by default, all 8 neighbors are visited to see if a pixel is connected to the background:

Return a 4-connected perimeter using CornerNeighbors->False:

In 3D, by default, all 26 neighbors are visited to see if a pixel is connected to the background:

Use CornerNeighbors->False to return a 6-connected perimeter:

Padding  (1)

By default, zero padding is assumed:

Specify a different padding:
