dilate - Morphological dilation of binary images
Calling Sequence
- E = dilate(Img, [SE, center])
Input Parameters
-
Img:
M x N Binary image to be dilated. (0 for background, 1 for object)
-
SE:
Arbitrary structuring element represented as a binary array. Defaults to M x N Binary dilated image.
-
center:
origin of structuring element. Shold be within image dimensions. Defaults to the center of the SE array.
Output Parameters
-
E:
M x N Binary dilated image.
Description
Function dilate performs morphological dilation of a binary image Img using SE as the structuring element.
Examples
Img = imread(SIPDIR+'images/tru.jpg');
Img = 1-im2bw(Img, 0.3);
Img = thin(Img);
xbasc()
imshow(Img, 2);
e = dilate(Img);
xbasc()
imshow(e, 2);
SE = eye(10,10);
e = dilate(Img, SE, [1,1]);
xbasc()
imshow(e, 2);

Remarks
The algorithm is fully functional, but there
exists many better ones. The present implementation
will certainly change, but the interface
shall remain unaltered.
