getsequence - Sequence of decomposed structuring elements
Syntax
SEQ = getsequence(SE)
Description
SEQ = getsequence(SE) returns
the array of structuring elements SEQ, containing
the individual structuring elements that form the decomposition of
SE. SE can be an array of structuring
elements. SEQ is equivalent to SE,
but the elements of SEQ have no decomposition.
Class Support
SE and SEQ are arrays
of STREL objects.
Examples
The strel function uses decomposition for
square structuring elements larger than 3-by-3. Use getsequence to
extract the decomposed structuring elements.
se = strel('square',5)
se =
Flat STREL object containing 25 neighbors.
Decomposition: 2 STREL objects containing a total of 10 neighbors
Neighborhood:
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
seq = getsequence(se)
seq =
2x1 array of STREL objectsUse imdilate with the 'full' option
to see that dilating sequentially with the decomposed structuring
elements really does form a 5-by-5 square:
imdilate(1,seq,'full')
