idilate

Morphological dilation

out = idilate(im, se, options) is the image im after morphological dilation with the structuring element se.

out = idilate(im, se, n, options) as above but the structuring element se is applied n times, that is n dilations.

Options

'border'	the border value is replicated (default)
'none'	pixels beyond the border are not included in the window
'trim'	output is not computed for pixels where the structuring element crosses the image border, hence output image had reduced dimensions.
'wrap'	the image is assumed to wrap around, left to right, top to bottom.

Cheaper to apply a smaller structuring element multiple times than one large one, the effective structuring element is the Minkowski sum of the structuring element with itself N times.
Windowing options of IMORPH can be passed.
