dilate

Morphological dilation of binary images

Calling Sequence

E = dilate(Img, [SE, center])

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.

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);
clf
imshow(Img, 2);

e = dilate(Img);
clf
imshow(e, 2);

SE = eye(10,10);
e = dilate(Img, SE, [1,1]);
clf
imshow(e, 2);
