The function dilates the source image using the specified structuring element that determines the shape of a pixel neighborhood over which the maximum is taken:
.. math::
\max _{(x',y') \, in \, \texttt{element} }src(x+x',y+y')
The function supports the in-place mode. Dilation can be applied several (
``iterations``
) times. For color images, each channel is processed independently.
