Name
morphClose - morphological grayscale close on an image.
Syntax
morphClose <-a | -b> <struct_element> <inimage> <outimage>
Description
morphClose calculates the morphological operation
Close, on the image inimage, with a structuring
element given by struct_element (in combination with
option -a or -b). The result is sent to the image
spesified in outimage.
The actual calculation is performed with the
expression:
outband = morphErode(morphDilate(inband))
Restrictions
Input images must be of the following types:
-
inimage
- Unsigned byte.
-
struct_element
- With option -a: Ascii characters (numbers) describing the
structuring element. With option -b: BIFF image with pixel
type signed short.
Options
-
-a struct_element
- struct_element is an ascii file which contains the
structuring element. See ascii2biff(1) for file format.
-
-b struct_element
- struct_element is a BIFF image which contains the
structuring element.
