Dilate image
dilates the grayscale, binary, or packed binary image J
= imdilate(I
,SE
)I
,
returning the dilated image, J
. SE
is a
structuring element object or array of structuring element objects, returned by the
strel
or offsetstrel
functions.
imdilate
automatically takes advantage of the decomposition of a
structuring element object (if it exists). Also, when performing binary dilation with a
structuring element object that has a decomposition, imdilate
automatically uses binary image packing to speed up the dilation.
Dilation using bit packing is described in [3].
