edilate - Euclidean morphological dilation of binary
Calling Sequence
- Dil = edilate(Img, [radius, form])
Input Parameters
-
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.
Output Parameters
Description
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.
Examples
Img = gray_imread(SIPDIR+'images/tru.jpg');
Img = 1-im2bw(Img, 0.3);
xbasc()
imshow(Img,2);
e = edilate(Img,7);
xbasc()
imshow(e,2);
