MorphologicalPerimeter

Updated In 8 Graphic
MorphologicalPerimeter[image]
picks out the morphological perimeter of regions of foreground in image.
MorphologicalPerimeter
treats values above t as foreground.
  • MorphologicalPerimeter yields a binary image in which pixels considered to be on the morphological perimeter have value 1 and others have value 0.
  • The morphological perimeter is defined to consist of foreground pixels that are directly adjacent to the background.
  • MorphologicalPerimeter works with binary, grayscale, and multichannel images, as well as real arrays of any rank.
  • The option setting CornerNeighbors->False treats only the four pixels in the coordinate directions as adjacent.

This returns only foreground pixels that are 4-connected to the background, effectively finding an 8-connected perimeter:
