inimage,with a structuringelement given by
struct_element(in combination withoption
-aor
-b).The result is sent to the imagespesified in
outimage.The actual calculation is performedwith the expression:
outband = morphDilate(morphErode(inband))
RESTRICTIONS
Input images must be of the following types:
- inimage
- Unsigned byte.
- struct_element
- With option -a:Ascii characters (numbers) describing thestructuring element. With option -b:BIFF image with pixeltype signed short.
OPTIONS
- -a struct_element
- struct_elementis an ascii file which contains thestructuring element. See ascii2biff(1) for file format.
- -b struct_element
- struct_elementis a BIFF image which contains thestructuring element.
