<br></div>
dim is the dimension of the image - in your case, it's 3.<br>
size is the size of the structuring element. It can be an integer or an itk.Size[dim] \
or a python sequence of length dim. If it's an integer, the size will be the same \
on the 3 dimensions. With the itk.Size or with the python sequences, the size can be \
different on the dimensions.<br>
<br>
Ex:<br>
<br>
k1 = itk.FlatStructuringElement[3].Ball(5)<br>
k2 = itk.FlatStructuringElement[3].Ball([5, 5, 5])<br>
size = itk.Size[3]()<br>
size[0] = size[1] = size[2] = 5<br>
k3 = itk.FlatStructuringElement[3].Ball(size)<br>
<br>
k1, k2 and k3 are the same in that example.<br><font color="#888888">

Hi,<br>
<br>
I am using the GrayscaleErodeImageFilter, but my ITK not have \
BinaryBallStructuringElement to use SetKernel().<br> <br>
how can I use SetKernel () ?<br>
<br>
code:<br>
erode = itk.GrayscaleErodeImageFilter.IF3IF3SE3.New()<br>
erode.SetInput(image.GetOutput())<br>
erode.SetKernel( ?? )<br>
<br>
<br>
Hi,<br>
<br>
BinaryBallStructuringElement is not used any more in wrappers.<br>
You can produce a structuring element with:<br>
i. itk.strel(dim, size) - it's a shortcut to produce a ball structuring element \
inherited of the time when creating a ball structuring element was requiring several \
lines of code;<br> ii. itk.FlatStructuringElement[dim].Ball(size). A few more methods \
are available in that class to produce box, annulus, ... structuring elements.<br> \
