Reflect structuring element

Syntax

SE2 = reflect(SE)

Description

SE2 = reflect(SE) reflects the structuring element (or structuring elements) specified by SE. This method reflects the structuring element through its center. The effect is the same as if you rotated the structuring element's domain 180 degrees around its center (for a 2-D structuring element).

Create a structuring element.

se = strel([0 0 1; 0 0 0; 0 0 0])
se = 
strel is a arbitrary shaped structuring element with properties:

      Neighborhood: [3×3 logical]
    Dimensionality: 2

Look at the neighborhood.

se.Neighborhood
ans = 3×3 logical array

   0   0   1
   0   0   0
   0   0   0

Reflect it.

se2 = reflect(se)
se2 = 
strel is a arbitrary shaped structuring element with properties:

      Neighborhood: [3×3 logical]
    Dimensionality: 2

Look at the reflected neighborhood.

se2.Neighborhood
ans = 3×3 logical array

   0   0   0
   0   0   0
   1   0   0
Open Live Script

Create an offsetstrel structuring element.

se = offsetstrel("ball",5,6.5)
se = 
offsetstrel is a ball shaped offset structuring element with properties:

            Offset: [11×11 double]
    Dimensionality: 2

Reflect the structuring element.

se2 = reflect(se)
se2 = 
offsetstrel is a ball shaped offset structuring element with properties:

            Offset: [11×11 double]
    Dimensionality: 2

Input Arguments

collapse all

Structuring element, specified as a strel or offsetstrel object or array of objects. If SE is an array of structuring element objects, then reflect reflects each element of SE.

Output Arguments

collapse all

Reflected structuring element, returned as a strel or offsetstrel object or array of objects. SE2 has the same size as SE.
