Hello ImageJ Users,

Is there any way to dilate or erode a binary image in one axis/direction
only, rather than symmetrically around the objects?
The binary images I'm using are primarily shapes with 90 or 180 degree
corners, i.e. not many rounded shapes.

I've considered shifting  duplicate images along one axis and ORing with
the original image, but the run time starts to get very long when
processing large numbers of images.

Any suggestions would be much appreciated.

Thanks.
