getsequence

Sequence of decomposed structuring elements

getsequence will be removed in a future release. See strel for the current list of methods.

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.

Examples

Decompose Square Structuring Element

Create a 5-by-5 structuring element.

se = strel("square",5)

se = 

strel is a square shaped structuring element with properties:

      Neighborhood: [5×5 logical]
    Dimensionality: 2

The strel function uses decomposition for square structuring elements larger than 3-by-3. Use getsequence to extract the decomposed structuring elements.

seq = getsequence(se)

seq = 

  2×1 strel array with properties:

    Neighborhood
    Dimensionality

Use imdilate with the "full" option to confirm that dilating sequentially with the decomposed structuring elements forms a 5-by-5 square:

imdilate(1,seq,"full")

ans =

     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

Input Arguments

SE — Structuring elements

array of strel objects

Structuring elements, specified as an array of strel objects.

Output Arguments

SEQ — Decomposed structuring elements

array of strel objects

Decomposed structuring elements, returned as an array of strel objects. The elements of SEQ have no further decomposition.
