Euclidean morphological dilation of binary

Dil = edilate(Img, [radius, form])

- Img
- M x N Binary image to be dilated. (0 for background, 1 for object)
- radius
- of circular euclidean structuring element to be used. Defaults to 5.
- form
- determines the size of
`Dil`

. It assumes be one of the following values:- 'same'
`Dil`

has the same size as the original image,`M x N`

. The image is assumed to be 0 outside its bounds.- 'full'
- Dil contains the full dilation,
`(M+2*radius-1) x (N+2*radius-1)`

. The image is assumed to be 0 outside its bounds.

- Dil
- Resultant image.

Function `edilate`

performs exact euclidean dilation of a binary image `Img`

using a circle as the structuring element. It is implemented in C to be fast.
