# getstructuringelementcv

Gets a structuring element that can be used for morphological commands on an image.

## Syntax

R = getstructuringelementcv(shape, kernelsize)

R = getstructuringelementcv(shape, kernelsize, anchor)

## Inputs

`shape`- Shape of
`R`. Valid values are: `kernelsize`- Vector of two positive integers representing [width, height] of
`R`. `anchor`- Optional vector of 2 integers specifying anchor position of the element. Default value
is [-1 -1], indicating the center of the kernel. Only option 2 of
`shape`depends on`anchor`.

## Outputs

- R
- Handle of the resulting structural element.

## Example

Get the structuring element which can be used in dilation:

```
handle = imreadcv('image1.jpg');
kernel = getstructuringelementcv(1, [10 10]);
result = dilatecv(handle, kernel, [-1 -1], 1, 0, [255 0 0]);
```
